Programmable logic controllers (PLCs) have been used extensively and are offered in terms of functions, program memories, and the number of inputs/outputs (I/Os), ranging from a few to thousands. With a focus on how to design and implement a PLC, this set explains hardware and associated basic concepts, intermediary and advanced concepts of PLC (using PIC16F1847 microcontroller). Flowcharts are provided to help the understanding of macros (instructions). Twenty application examples to show how to use the PIC16F1847-Based PLC in different control applications, related files for hardware and software components, and appendices are also provided. Aimed at researchers and graduate students in electrical engineering, power electronics, robotics and automation, sensors, this book: Explains how to design and use a PIC16F1847 microcontroller-based PLC including easy to use software structures. Covers concepts like Contact and Relay Based Macros, Flip-Flop Macros, Timer Macros, Counter Macros and Comparison Macros. Presents arithmetical and logical macros to carry out arithmetical and logical operations to be used for 8-bit or 16-bit variables and/or constant values. Illustrates program control macros to enable or disable a block of PLC program or to move execution of a program from one place to another. Discusses the implementation of Sequential Function Chart (SFC) elements with up to 24 steps.

Tras el éxito de la sección Banco de Circuitos en mi sitio y colecciones agotadas de'Circuitos e Informaciones'y'Circuitos y Soluciones', llevo a mis lectores una colección de circuitos seleccionados de mi enorme colección de documentos técnicos y libros. Durante toda mi vida he recogido casi todas las revistas técnicas de electrónica extranjeras, de Estados Unidos, Francia, España, Italia, Alemania, Argentina y Japón incluso, que poseen un gran acervo técnico. Los circuitos principales de estas publicaciones son seleccionados comprobando que puede montarse en nuestros días, con una posible indicación de componentes equivalentes, haciendo cambios que creo son necesarios y ponerlos a disposición de nuestros lectores. De hecho, circuitos básicos con componentes discretos comunes, transistores en circuitos integrados, son todavía ampliamente utilizados como una solución simple para problemas inmediatos, parte de los proyectos más avanzados y fin incluso didáctico teniendo en cuenta la solicitud de un maestro que requiere una aplicación a una teoría. Por lo tanto, estamos nuevamente con esta serie, pero con una estructura diferente, nuevos proyectos y nuevo enfoque. La diferencia de enfoque será dividir los diversos volúmenes de la serie de temas.

In this volume, we have put together papers spanning a broad range — from the area of modeling of strain and misfit dislocation densities, microwave absorption characteristics of nanocomposites, to X-ray diffraction studies.Specific topics in this volume include:In summary, papers selected in this volume cover various aspects of high performance logic and circuits for high-speed electronic systems.

El término'colección de circuitos'fue abordado muchas veces durante nuestra larga trayectoria como escritor de artículos y libros técnicos, incluyendo también informaciones. Así que, antes, abordar este tema, publicamos'circuitos y informaciones'(7 volúmenes) y'Circuitos y Soluciones'(5 volúmenes) que contienen cientos de circuitos útiles e información técnica de todo tipo. Agotada la serie, los lectores comenzaron a cobrar nosotros algo similar hasta la fecha y que puede ser utilizado en proyectos de todas las clases. De hecho, circuitos básicos con componentes discretos comunes, transistores en circuitos integrados, son todavía ampliamente utilizados como una solución simple para problemas inmediatos, parte de los proyectos más avanzados y fin incluso didáctico teniendo en cuenta la solicitud de un maestro que requiere una aplicación a una teoría. Por lo tanto, estamos nuevamente con esta serie, pero con una estructura diferente, nuevos proyectos y nuevo enfoque. La diferencia de enfoque será dividir los diversos volúmenes de la serie de temas. Así, en nuestro primer estamos abordando circuitos de audio, e después, en la serie, fuentes y en el tercer circuito, después circuitos osciladores y así sucesivamente.

Para esta edición hemos elegido otro envío con 100 circuitos que pueden en fuentes de alimentación de los más diversos circuitos e aparatos como punto de partida, en algunos casos requiriendo sólo modificaciones o actualizaciones a los valores de los componentes. Tras el éxito de la sección Banco de Circuitos en mi sitio y colecciones agotadas de'Circuitos e Informaciones'y'Circuitos y Soluciones', llevo a mis lectores una colección de circuitos seleccionados de mi enorme colección de documentos técnicos y libros.

During the long career of the author as a writer of technical articles and books, he have on several occasions addressed the theme'collection of circuits', also including information. Thus, previously, addressing this theme, he published the series'Circuits and Information'(7 volumes) and'Circuits and Solutions'(5 volumes) containing hundreds of useful circuits and technical information of all kinds. The series has run out, time has passed, but readers still charge us something similar updated and that can still be used in projects of all kinds. In fact, basic circuits using ordinary discrete components, from transistors to integrated circuits, are still widely used as simple solutions for immediate problems, part of more advanced projects and even for didactic purposes, at the request of a teacher who needs an application for a theory. So, he is back with this series, but with a differentiated structure, new projects and a new approach. The difference in approach will be to divide the various volumes of the series by themes, we will have audio circuits,such as amplifiers, preamplifiier, mixers, etc. In his stock of circuits, collected from all possible sources, he already have more than 12,000 of them, many of which can be accessed in a dispersed way in the site of the author. The advantage of having these circuits organized in volumes, besides access anywhere, is in the easy location of a circuit. The information, on the other hand, will be added to the circuits, with internal links, which is only possible in a digital publication. Most of these circuits, collected in publications that, in some cases, may not be very current, receive a special treatment with comments, suggestions and updates that make possible its execution even in our days.

Diese dritte Auflage bietet einen vollständig überarbeiteten Blick auf alle Aspekte der integrierten digitalen Schaltungstechnik. Aufbauend auf der Halbleiterphysik moderner CMOS-Transistoren und deren Herstellung werden digitale und wenn nötig analoge Grundschaltungen behandelt. Weiter werden Funktionsblöcke wie Speicherschaltungen, Addierer und Multiplizierer besprochen. Als neuer Schwerpunkt der dritten Auflage ziehen sich die Auswirkungen der zeitlichen und örtlichen Schwankungen der Versorgungsspannungen und der Temperatur sowie die Einflüsse der herstellungsbedingten Schwankungen der Transistorparameter wie ein roter Faden durch alle Kapitel. Methoden zur Minimierung der Verlustleistung bilden einen weiteren neuen Schwerpunkt des Buches. Es wird, wie in den bisherigen Auflagen, die technologieorientierte und die systemorientierte Schaltungstechnik gemeinsam und zusammenhängend dargestellt.
