Het boek beschrijft de werking van digitale circuits vanaf schakelingen met poorten tot aan de werking van een processor. Van elke schakeling of systeem kan de werking worden gesimuleerd. Hierbij wordt het gedrag van componenten en het verloop van signalen in de tijd op ingangen, uitgangen en relevante verbindingslijnen zichtbaar gemaakt. Zo wordt in detail gevisualiseerd wat het gedrag is van de hardware als er een instructie wordt uitgevoerd.
Het boek is opgebouwd uit drie modules die de volgende onderwerpen behandelen:
Basismodule
Poorten en combinatorische schakelingen.
Hoe rekent een computer?
Hoe werkt een rekenmachine?
Module Digitale Techniek
Hoe ontwerp je combinatorische schakelingen m.b.v. Boole-algebra?

The 8x10" iFixit Magnetic Project Mat catches and securely holds screws as you pull them out of a device. Now you can stop worrying about keeping track of all the loose screws and focus on your repair. Screws and small parts will remain right where you left them. For laptops with hundreds of screws, use the whole mat as a screw guide and keep careful location notes.
Included is a pen — made by Staedtler, producer of top-of-the-line pens and pencils for artists and architects — that was specially designed for the Project Mat. The Lumocolor Correctable pen resists smears and won't wipe away with a casual brush of your hand. When your repair is complete, use the eraser tip or a dry cloth to wipe the ink away clean.

The short-wave technique has a very particular appeal: It can easily bridge long distances. By reflecting short-wave signals off the conductive layers of the ionosphere, they can be received in places beyond the horizon and therefore can reach anywhere on earth. Although technology is striving for ever higher frequencies, and radio is usually listened to on FM, DAB+, satellite or the Internet, modern means of transmission require extensive infrastructure and are extremely vulnerable. In the event of a global power outage, there is nothing more important than the short-wave. Amateur radio is not only a hobby, it’s also an emergency radio system!
Elektor’s SDR-Shield is a versatile shortwave receiver up to 30 MHz. Using an Arduino and the appropriate software, radio stations, morse signals, SSB stations, and digital signals can be received.
In this book, successful author and enthusiastic radio amateur, Burkhard Kainka describes the modern practice of software defined radio using the Elektor SDR Shield. He not only imparts a theoretical background but also explains numerous open source software tools.
Menno van der Veen is well known for his research publications on tube amplifiers used in audio systems.
In this book he describes one of his research projects which focuses on the question of whether full compensation for distortion in tubes and output transformers is possible.
In the past, a variety of techniques have been developed. One of them has largely been forgotten: trans-conductance, which means converting current into voltage or voltage into current. Menno van der Veen has breathed new life into this technique with his research project titled “Trans”. This book discusses all aspects of this method and discusses its pitfalls. These pitfalls are addressed one by one. The end result is a set of stringent requirements for Trans amplifiers.
Armed with these requirements, Menno then develops new Trans amplifiers, starting with Transie 1 and Transie 2. These DC-coupled, single-ended tube amplifiers have unusually good characteristics and are suitable for hobbyist construction. Next the Trans principle is applied to amplifiers with higher output power.
A trial-and-error process ultimately leads to the Vanderveen Trans 30 amplifier, which optimizes the features of Trans. The characteristics of this amplifier are so special and unique that Menno believes he has struck gold. To ensure that variations in tube characteristics cannot interfere with optimal Trans behavior, Menno makes use of simulations and comparison with other amplifier types. This book reads like an adventure story, but it is much more – it is an account of solid research into new ways to achieve optimal audio reproduction.
ARM Cortex-M Embedded Design from 0 to 1
Hobbyists can mash together amazing functional systems using platforms like Arduino or Raspberry Pi, but it is imperative that engineers and product designers understand the foundational knowledge of embedded design. There are very few resources available that describe the thinking, strategies, and processes to take an idea through hardware design and low-level driver development, and successfully build a complete embedded system. Many engineers end up learning the hard way, or never really learn at all.
ARM processors are essentially ubiquitous in embedded systems. Design engineers building novel devices must understand the fundamentals of these systems and be able to break down large, complicated ideas into manageable pieces. Successful product development means traversing a huge amount of documentation to understand how to accomplish what you need, then put everything together to create a robust system that will reliably operate and be maintainable for years to come.
This book is a case study in embedded design including discussion of the hardware, processor initialization, low‑level driver development, and application interface design for a product. Though we describe this through a specific application of a Cortex-M3 development board, our mission is to help the reader build foundational skills critical to being an excellent product developer. The completed development board is available to maximize the impact of this book, and the working platform that you create can then be used as a base for further development and learning.
The Embedded in Embedded program is about teaching fundamental skill sets to help engineers build a solid foundation of knowledge that can be applied in any design environment. With nearly 20 years of experience in the industry, the author communicates the critical skill development that is demanded by companies and essential to successful design. This book is as much about building a great design process, critical thinking, and even social considerations important to developers as it is about technical hardware and firmware design.

Using Visual Basic as Rapid Application Development tool we will take you on a journey to unlock the world beyond the connectors of the PC.
After familiarising yourself with Visual Basic, its development environment and the toolset it offers, items such as serial communications, printer ports, bit-banging, protocol emulation, ISA, USB and Ethernet interfacing and the remote control of test-equipment over the GPIB bus, are covered in extent. Each topic is accompanied by clear, ready to run code, and where necessary, schematics are provided that will get your projects up to speed in no time.
This book will show you advanced things like: using tools like Debug to find hardware addresses, setting up remote communication using TCP/IP and UDP sockets and even writing your own internet servers. Or how about connecting your own block of hardware over USB or Ethernet and controlling it from Visual Basic. Other things like internet-program communication, DDE and the new graphics interface of Windows XP are covered as well.
All examples are ready to compile using Visual Basic 5.0, 6.0, NET or 2005. Extensive coverage is given on the differences between what could be called Visual Basic Classic and Visual basic .NET / 2005.

Dit boek is bedoeld voor diegenen die zich bezig houden met geluidsversterking en geluidsdistributie. Het gaat in op de akoestische eigenschappen van open, halfopen en omsloten ruimten. Belangrijk is hoe luidsprekers aangepast kunnen worden op allerlei omgevingen. Meestal moet men een keuze maken uit het aanbod van luidsprekers en microfoons. De vraag is dan welke luidspreker en microfoon de juiste keuze zijn. En hoe deze moeten worden opgesteld waarbij spraak- en muziekverstaanbaarheid en de maximaal haalbare versterking in de live-situatie de belangrijkste criteria zijn. Dit boek geeft antwoord op die vragen.
Verder wordt de lezer meegenomen naar het ontwerpen van luidsprekers op basis van de T/S parameters. Met eenvoudige software is het mogelijk akoestische en mechanische elementen van een luidspreker met de eventuele behuizing te vertalen naar de elektrische analogieën, zodat de luidspreker op de PC gesimuleerd kan worden. Aan de hand van rekenvoorbeelden worden bovenstaande simulaties ondersteund. Tot slot zijn in de referentielijst een aantal internetlinks opgenomen waaruit zeer waardevolle gegevens gehaald kunnen worden.
De auteur, Peter Swarte, is natuurkundig ingenieur en was werkzaam bij Philips. Momenteel is hij_eigenaar van consultancy bureau P.A.S. Electro Acoustics en is hij actief lid van zowel het NAG (Nederlands Akoestisch Genootschap) als de AES (Audio Engineering Society).

Arduinonext is an initiative powered by an electronics and microcontrollers specialist team aiming to help all those who are entering in the technology world, using the well-known Arduino platform to take the next step in electronics.
We strive to bring you the necessary knowledge and experience for developing your own electronics applications; interacting with environment; measuring physical parameters; processing them and performing the necessary control actions.
This is the first title in the 'Hands-On' series in which Arduino platform co-founder, David Cuartielles, introduces board programming, and demonstrates the making of an 8-bit Sound Generator.
The author, Johan Basse Bergqvist, is an engineer, a musician, and an audiophile with a knack for building projects that produce the desired results. The combination of these skills leads to a uniquely valuable perspective on audio design that is routinely reflected in the book and passed on to the readers.
Several design projects are provided, 40 in total. The designs are explained, and the unique features or methods he uses are described in further detail. Each design includes detailed schematics and a complete parts list. Many of the projects also include layout documentation in the form of CAD photos of the PCB layouts. The range of projects is very diverse and includes something that will appeal to everyone. Stereo amplifiers, guitar and bass amplifiers, preamplifiers for phono, and microphones are all covered. Several variants for each type are included, and the power amplifier designs range from a few watts to several hundred watts, which meet almost any power level you might tackle.
This book is for people who want to understand how AC drives (also known as inverter drives) work and how they are used in industry by showing mainly the practical design and application of drives.
The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The different parts of an AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection.
An important part of the book gives details of the features and functions often found in AC drives and gives practical advice on how and where to use these. Also described is future drive technology, including a matrix inverter.
The mathematics is kept to an essential minimum. Some basic understanding of mechanical and electrical theory is presumed, and a basic knowledge of single andthree phase AC systems would be useful.
Anyone who uses or installs drives, or is just interested in how these powerful electronic products operate and control modern industry, will find this book fascinating and informative.
