Het boek Programmeerbare Logica neemt je mee op een ontdekkingstocht door de wereld van de digitale elektronica. Na het leggen van een grondige basis is er uitgebreid aandacht voor het maken van logische circuits. Auteur Vincent Himpe toont o.a. hoe je met bestaande bouwstenen logische elektronica systemen maakt. Hij laat verder zien hoe je om gaat met de interfacing met de buitenwereld. Hierbij komen stroomvoorziening, bord layout en beveiliging uitvoerig aan bod. Moderne logische systemen zijn zo complex dat het ontwerpen met kleine bouwstenen zoals losse poortjes, flipflops en tellers een haast onbegonnen zaak geworden is. Daarom gaat Himpe in de tweede helft van het boek in op de programmeerbare logica zoals CPLD en FPGA. Hij belicht een ontwerpmethode waarmee je snel de brug slaat tussen het klassieke ontwerp en het ontwerp in FPGA. Naast schematisch ontwerp komt ook het ontwerpen met synthesetalen zoals Verilog en VHDL aan de orde. Ter afsluiting wordt een project (een klok met alarmfunctie) geïmplementeerd in Verilog en VHDL. Ook het fysieke ontwerp met deze logische componenten komt aan bod. Hoe programmeer je deze en wat zijn de randvoorwaarden zoals stroomvoorziening en signaalconditionering. De inhoud van het boek is 'state of the art'. En alles wat besproken wordt is direct implementeerbaar met de gratis ontwikkelomgeving Quartus van Altera. Over de auteur Vincent Himpe (B) leeft sinds 2005 in San Jose – hartje Silicon Valley – en werkt aan de ontwikkeling van nieuwe harddisktechnologie en de chips.Himpe heeft meerdere patenten en over de jaren verschillende artikelen gepubliceerd in onder andere IMeko / TSCC, The Journal of Computer Standards AND Interfaces, Elektor en EDN. Hij is ook auteur van de bestseller 'Visual Basic for electronic engineering applications' uitgegeven door Elektor.

This book is intended for electronics enthusiasts and professionals alike, who want a much deeper understanding of the incredible technology conquests over the pre-digital decades that created video. It details evolution of analogue video electronics and technology from the first electro-mechanical television, through advancements in Cathode Ray Tubes, transistor circuits and signal processing, up to the latest analogue, colour-rich TV, entertainment devices and calibration equipment. Key technological advances that enabled monochrome video and, eventually, colour are explained. The importance, compromises and techniques of maintaining crucial backward legacy compatibilities are described. The generation, signal processing and playback of analogue video signals in numerous capture, display, recording and playback devices together with operating principles and practices are examined. Technical and, often, political merits and deficiencies of key national and international video standards are highlighted. Several formats are shown to win and ultimately to co-exist. This book begins at fairly basic levels; concepts are introduced with human physiological perceptions of light and colour explained. This leads to the subject matter of luminance and chrominance; their equations and the circuits to process. There is full, detailed analysis of waveform shapes and timings inside video equipment and relevant popular connections e.g. S-video. Several analogue video projects which you can build yourself are also included in this book; with schematics, circuit board layouts and calibration steps to help you obtain the best results. The book makes use of many colour pages where the subject matter demands it (e.g. test cards). If you really want a deeper understanding of analogue video then this book is for you!

Pfiffige Projekte zum Messen, Steuern und Regeln Der Raspberry Pi dominiert seit vielen Jahren die Maker-Szene. Frei verfügbare I/O-Pins machten ihn zu einem der beliebtesten Prozessorboards aller Zeiten. Allerdings verfügt der klassische Raspberry Pi über keinerlei Analogeingänge. Eine direkte Messung analoger Werte ist damit nicht möglich. So können weder Photodioden noch NTCs oder Hallsensoren etc. unmittelbar ausgelesen werden. Zudem sind die Pins direkt, d. h. ohne Treiber oder Schutzschaltung, mit den freiliegenden Kontakten verbunden. Dadurch kann der zentrale Controller und damit der gesamte Raspberry Pi schnell zerstört werden. Mit dem Pico können diese Probleme elegant gelöst werden. Er kann als sogenanntes „Frontend“ problemlos vielfältige Messaufgaben übernehmen. Zudem ist der Pico deutlich preisgünstiger als ein klassischer Raspberry Pi 4. Falls eine Fehlbeschaltung zur Zerstörung des Pico führt, ist dies vor allem für nicht-professionelle Anwender relativ leicht zu verkraften. Der klassische Raspberry Pi und der Pico werden so zum idealen Duo. Das Buch führt entsprechend in das weite und hochaktuelle Gebiet der modernen Controllertechnik anhand der beiden Boards „Raspberry Pi 4“ und „Raspberry Pi Pico“ ein. Neben einer tiefergehenden Einführung in die Arbeits- und Funktionsweise der Controllerboards selbst wird insbesondere auch auf die Messwerterfassung und -verarbeitung mit digitalen Prozessoren eingegangen. Insbesondere die Kombination beider Systeme bietet vielfältige und hochinteressante Möglichkeiten. Praktische Projekte aus dem Inhalt: USB-Verbindung zwischen Raspberry Pi 4 und Pico I²C-Kommunikation und Pico als I²C-Device Voltmeter und Computerthermometer Pico W als Web-Server und WLAN-Scanner Frequenzmesser und -generatoren OLED-Displays an Pico und Raspberry Pi 4 Energiesparmonitor Welche Astronauten sind im Orbit?

Valve Amplifiers are regarded by many to be the ne plus ultra when it comes to processing audio signals. The combination of classical technology and modern components has resulted in a revival of the valve amplifier. The use of toraidal-core output transformers, developed by the author over the past 15 years, has contributed to this revival. The most remarkable features of these transformers are their extremely wide frequency ranges and their very low levels of linear and nonlinear distortion. This book explains the whys and wherefores of toroidal output transformers at various technical levels, starting with elementary concepts and culminating in complete mathematical descriptions. In all of this, the interactions of the output valves, transformer and loudspeaker form the central theme. Next come the practical aspects. The schematic diagram of a valve amplifier often appears to be very simple at first glance, but anyone who has built a modern valve amplifier knows that a lot of critical details are hidden behind this apparent simplicity. These are discussed extensively, in connection with designs for amplifiers with output powers ranging from 10 to 100 watts. Finally, the author gives some attention to a number of special valve amplifiers, and to the theory and practice of negative feedback. In summary, this book offers innovative solutions for achieving perfect audio quality. Do-it-yourself builders, as well as persons who want to gain a deeper technical understanding of the complex world of audio transformers, valve amplifiers and audio signal processing, will find this book a rich and useful source of information.
