Analog and RF Circuits

By Ian Hickman

Hickman's latest guide is essential reading for anyone designing analog circuits. This book, along with the recent Analog Circuits Cookbook also available from Newnes, will enlighten, inform, interest and even amuse readers, and give them the ability to tackle analog and RF design problems with confidence.

Based on articles published in Electronics World, this book covers such topics as RF amplifiers, oscillator design and behaviour, waveform analysis, optoelectronics, filters and op-amps, as well as offering intriguing insights in chapters such as Cautionary Tales for Circuit Designers, Circuit Reflections and Is Matching Easy?

Ian Hickman is one of the world's leading analog and RF engineers. Using illustrations and examples rather than tough mathematical theory, Ian Hickman presents a wealth of ideas and tips based on his own workbench experience.

Electronic devices and circuits

By Salivahanan

Electronic devices and circuits surround our daily existence in an indispensible fashion. Thereby, the authors, in this book have attempted to reveal the complexities of the world of electronics in an extremely simplified manner, using pedagogical features to illustrate and exemplify the concepts thoroughly. This revised edition of Electronic Devices and Circuits is a treat for the young readers, and will generate and maintain an interest in the subject which will stimulate a sound learning.

Observe different types of keyboard and mouse and observe the internal circuits.

Keyboard

Wired Keyboard
Keyboards are an indispensable accessory for a computer. One of the most basic input devices, computer keyboards are used in navigation, execution of processes, programming and several other purposes. Several software based application directly derive their existence from a keyboard. For instance, social networking websites, programming languages, navigation over the computer menus etc. utilize a computer keyboard. Even this very article wouldn’t have been possible without a keyboard.
