Elektor Digital Ontwerpen van Buizenversterkers (E-book)
Ook in deze tijd klinken buizenversterkers nog steeds fantastisch, misschien wel mooier dan ooit. Nu hebben we immers de beschikking over moderne materialen als ringkern uitgangstransformatoren, uiterst hoogwaardige weerstanden en condensatoren en vele soorten goed klinkend draad. Ook de moderne geluidsbronnen als de CD speler en de nieuwste hoogwaardige luidsprekers laten beter dan ooit horen hoe goed de buizenversterker weergeeft.Dit boek van Menno van der Veen kijkt niet alleen theoretisch naar buizenversterkers, maar vooral ook naar de ontwerpfase waarin besluiten moeten worden genomen over de doelen en eisen van de versterker. Hoe hangen deze samen met subjectieve en objectieve criteria? Welke schakelingen klinken vooral prachtig en waarom doen ze dat? Stel dat je een versterker gaat ontwikkelen en in de handel wilt brengen, tegen welke problemen loop je dan aan? En wat te zeggen van het belang en de betekenis van metingen? Zeggen ze nu iets of zeggen ze niets? Dankzij de grote rekenkracht van de computer kunnen we tegenwoordig dieper meten dan ooit. Hoe pas je deze technieken toe bij buizenversterkers? Tot nu toe waren metingen over frequentiebereik en vermogen en vervorming voldoende om een beeld van de eigenschappen van een versterker te geven. Maar zijn zulke metingen voldoende of moeten we gaan meten zoals ons oor waarneemt, met echte muzieksignalen in plaats van meettoontjes? De auteur schetst een toekomst waarbij meten aan de versterker de eigenschappen van ons horen moet volgen om tot nieuwe inzichten te komen.Dit boek is meer op de praktijk gericht dan op de theorie en heeft een beschouwend karakter, alsof de auteur van bovenaf naar de buizenversterker kijkt. Kenniselementen worden geïntegreerd en in een breed overzichtelijk kader geplaatst.

Elektor Digital Oscilloscopes (E-book)
Understanding and Using Them Effectively What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope. Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back. In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals? Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.

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!

Elektor Digital Percer les mystères de l’électronique (E-book)
Le monde de l'électronique est à la fois vaste et… tout petit ! Voici un livre qui confirme ces deux constatations contradictoires. En effet, en électronique, tout touche à tout, d'une manière ou d'une autre. Le plus petit détail peut avoir les plus grandes conséquences, et pas toujours celles que l'on attendrait. L'objectif de l'auteur de cette série d'articles autonomes intitulée hors-circuits, réunis ici en un livre, n'est pas de vous tenir par la main. Robert Lacoste, électronicien professionnel de haut-niveau, vous donne des pistes pour comprendre ce qui paraît mystérieux. Il vous guide juste assez pour vous permettre ensuite de progresser tout seul. Avec lui, non seulement vous repousserez vos propres limites, mais saurez aussi détecter celles du matériel et du logiciel que vous utilisez. En vous invitant à repasser par les notions de physique de base, il vous permettra de séparer les véritables progrès techniques des laïus commerciaux. Les bases, ça peut mener loin D'où vient la sensibilité d'un récepteur d'ondes radio ? Pourquoi le téléchargement d'une vidéo sur votre portable est-il beaucoup plus lent à la campagne qu'en centre-ville ? Si pour vous la réponse technique à des questions comme celles-ci (et bien d'autres que vous n'osez peut-être même pas vous poser) n'est pas évidente, ce livre vous aidera à y voir plus clair. Oui, on peut être à l'aise avec les microcontrôleurs, mais dérouté par le comportement d'un simple transistor. Vous sentez-vous concerné par de telles interrogations ? Ce livre est donc pour vous. Sans aucune formule mathématique qui ne soit pas à la portée d'un lycéen, il balaye tout le champ de l'électronique, depuis l'analogique jusqu'au traitement numérique du signal en passant par le domaine si redouté des hautes-fréquences. La théorie ne s'y éloigne jamais beaucoup de la loi d'Ohm ! Avec des mots simples, l'auteur explique comment ça marche, pourquoi parfois ça ne marche pas comme on veut, et comment mieux utiliser différentes techniques dans vos propres projets pour que ça marche. Liste des sujets abordés : adaptation d'impédance : qu'est-ce-que c'est ? petite introduction aux microrubans jouons avec la réflectométrie temporelle circuits imprimés : éviter les bourdes en HF et avec les fréquences élevées le marquage CE pour les béotiens le quartz magie de la PLL VCO & PLL : pour obtenir des fréquences à la fois précises, stables et variables synthèse numérique directe : une introduction comprendre l'amplificateur à transistor : sexagénaire vaillant ampli de classe A, B, C, D, E, F, G, H : quesako ? le filtrage numérique sans stress : les filtres FIR le filtrage numérique sans stress : les filtres CIC le filtrage numérique sans stress : les filtres IIR l'ABC des CA/N DNL, INL, SNR, SINAD, ENOB, SFDR et consorts l'ABC des CA/N sigma-delta, quésaco ? bruit et sensibilité des récepteurs échange débit contre portée
