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).

If you have the right tools, designing a microprocessor shouldn’t be complicated. The Verilog hardware description language (HDL) is one such tool. It can enable you to depict, simulate, and synthesize an electronic design, and thus increase your productivity by reducing the overall workload associated with a given project.Monte Dalrymple’s Microprocessor Design Using Verilog HDL is a practical guide to processor design in the real world. It presents the Verilog HDL in a straightforward fashion and serves as a detailed introduction to reducing the computer architecture and as an instruction set to practice. You’re led through the microprocessor design process from start to finish, and essential topics ranging from writing in Verilog to debugging and testing are laid bare.The book details the following, and more: Verilog HDL Review: data types, bit widths/labeling, operations, statements, and design hierarchy Verilog Coding Style: files vs. modules, indentation, and design organization Design Work: instruction set architecture, external bus interface, and machine cycle Microarchitecture: design spreadsheet and essential worksheets (e.g., Operation, Instruction Code, and Next State) Writing in Verilog: choosing encoding, assigning states in a state machine, and files (e.g., defines.v, hierarchy.v, machine.v) Debugging, Verification, and Testing: debugging requirements, verification requirements, testing requirements, and the test bench Post Simulation: enhancements and reduction to practice Monte Dalrymple received a BSEE (with highest honors) and an MSEE from the University of California at Berkeley, where he was elected to Phi Beta Kappa. Monte started his career at Zilog, where he designed a number of successful products, including the Serial Communication Controller (SCC) family and the Universal Serial Controller (USC) family. He was also the architect and lead designer of the Z380 microprocessor. Monte started his own company, Systemyde International Corp., in 1995, and has been doing contract design work ever since. He designed all five generations of Rabbit microprocessors, a Z180 clone that is flying on the Juno mission to Jupiter, and a Z8000 clone that flies in a commercial avionics air data computer. Monte holds 16 patents as well as both amateur and commercial radio licenses. Monte wrote 10 articles for Circuit Cellar magazine between 1996 and 2010. He recently completed a side project to replace the CPU in an HP-41C calculator with a modern FPGA-based version.

A Small Basic Approach There are many different PC programming languages available on the market. Some have beautiful names; some have easy to use development tools. Others have incredible power. They all have one thing in common: they assume that you have, or want to have, a knack for technology and difficult to read commands. In this book we take a practical approach to programming. We assume that you simply want to write a PC program, and write it quickly. Not in a professional environment, not in order to start a new career, but for plain and simple fun... or just to get a task done. Therefore we use Small Basic. You will have an application up and running in a matter of minutes. You will understand exactly how it works and be able to write text programs, graphical user interfaces, and advanced drivers. It is so simple; you don't even need to be an adult!
