Description

Practical Digital Electronics for Technicians covers topics on analog and digital signals, logic gates, combinational logic, and Karnaugh mapping.
The book discusses the characteristics and types of logic families; sequential systems including latch, bistable circuits, counters and shift registers; Schmitt triggers and multivibrators; and MSI combinational logic systems. Display devices, including LED, LCD and dot matrix display; analog and digital conversion; and examples of and equipment for digital fault finding are also considered. The book concludes by providing answers to the questions from each chapter.
Electronics technicians and students engaged in electronics courses will find the book useful.
