Es gibt wohl kaum noch jemanden, der den außerordentlich guten Klang von Röhrenverstärkern ernsthaft bezweifelt. Sie klingen lebendig, durchzeichnet, produzieren räumliche Tiefe, ihr Klangbild ist unaufdringlich angenehm, und im Hinblick auf die entwickelte Dynamik scheinen sie keinerlei Einschränkungen zu kennen. In einer systematisch-theoretischen Untersuchung geht der Autor den Ursachen dieser Kennzeichen nach. Die Kopplung zwischen Endröhren und Ausgangsübertragern wird mit der erforderlichen Tiefe dargestellt. Die formulierten Stabilitätsbedingungen müssen moderne, hochwertige Verstärker mindestens erfüllen. Besonders hervorzuheben an diesem Buch ist, dass es sich nicht allein auf die Darstellung technisch nackter Fakten beschränkt. Der Autor versteht es gleichermaßen spannend und anschaulich zu berichten, dass das Entwickeln von Röhrenverstärkern durchaus in unser alltägliches Dasein eingreifen kann. Ja, selbst der Nutzen von Patenten wird angesprochen. Neue Theorien und neue Lösungen für eine perfekte Audioqualität mit Röhrenverstärkern sind Gegenstand dieses Buches. Sowohl der ambitionierte Selbstbauer, als auch derjenige, der seine Kenntnisse und Einsichten in die Zusammenhänge vertiefen möchte, wird dieses Buch mit Gewinn zur Hand nehmen. Update Auf Seite 322 sind die Bilder 12.4.2 und 12.4.3 identisch; das ist falsch. Das korrekte Bild 12.4.3 steht unter "Downloads" zur Verfügung.

Practical Multitasking Fundamentals Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation? Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs. Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher. Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project. What you will learn: How preemptive scheduling works within FreeRTOS The Arduino startup “loopTask” Message queues FreeRTOS timers and the IDLE task The semaphore, mutex, and their differences The mailbox and its application Real-time task priorities and its effect Interrupt interaction and use with FreeRTOS Queue sets Notifying tasks with events Event groups Critical sections Task local storage The gatekeeper task

From SRPP and Mu-Follower to OTL Designs Tube amplifiers suffer from distortion. Fortunately, circuits such as the SRPP amplifier, mu-follower, and beta-follower produce minimal distortion even at output voltages of 50 to 100 Vpeak. These designs are often published with errors. Without a sound understanding of the theory, it is easy to arrive at a flawed design. In the first section of this book, we investigate the origin of distortion, while in the second we investigate the design of and SRPP and a mu-follower. On the internet we can find the most exotic designs. Evaluating them teaches us that these designs often make matters worse rather than better. In the chapter on incorrect SRPPs and mu-followers, we sometimes see bizarre and misguided designs where using a simple single-triode amplifier would perform much better. Push-pull output stages also exist. A great number of them are examined, and their similarity to the SRPP is discussed. This is done especially with the help of the theory behind the OTL based on the ‘mother’ of all OTLs, the Philips HF303. Finally, attention is given to frequency characteristics and technical matters such as the supply voltage and the filament power supply. To illustrate these points, there are a few designs covering the subjects discussed. This book presents much new theory that has not been published before. It is often an eye-opener, showing that many things have a beautiful and unexpected simplicity.

50 maal 'elektronica van vroeger'. In het januarinummer 2005 van het elektronica-maandblad Elektor zag de rubriek 'Retrotronica' voor het eerst het licht. Onder supervisie van Elektor-redacteur Jan Buiting wordt sindsdien elke maand een stukje 'elektronica van vroeger' opgerakeld. Tegenwoordig worden de meeste elektronische schakelingen opgebouwd rond een microcontroller die het 'denkwerk' voor zijn rekening neemt. Nog niet zo heel lang geleden echter bestonden die dingen nog niet (of waren ze onbetaalbaar); niettemin slaagden de ontwerpers van toen er (naar huidige maatstaven) verbijsterend goed in om uiterst betrouwbaar en nauwkeurig werkende schakelingen en apparatuur te bouwen. Veel apparaten blijken, na jaren op een stoffige zolder of in een vochtige kelder te hebben gestaan, na een schoonmaakactie nog perfect te functioneren -- er is dus geen reden om de 'elektronica van vroeger' met een meewarige blik te bekijken; integendeel: het zijn vaak wondertjes van vernuft en vakmanschap! In dit boek hebben we 50 bijdragen uit de rubriek 'Retrotronica' voor u gebundeld - een must voor iedereen die geïnteresseerd is in 'oude' elektronica of in de geschiedenis van het maandblad Elektor (destijds Elektuur), aangezien enkele 'klassieke' Elektuur-schakelingen prominent aan bod komen!
