Preface

 

The main purpose of this handbook is a HANDS-ON APPROACH in learning digital circuits.

In each section, a digital chip is introduced and then a software/hardware circuit will follow. The software circuit can be implemented by electronic circuit design and simulation software such as Multisim .

 

The main goal of this handbook is to create a vast visualization of the working function of the digital electronics circuitries. Based on my experience in teaching electronics, students had more problems with setting up the hardware circuits than software circuits. Therefore, one of my main intentions in writing this handbook is to guide the students through setting up a complete wiring of the circuits.

 

This handbook is a COMPREHENSIVE COVERAGE of the practical working of the digital circuits and can be used as digital electronics textbook/lab manual in digital electronics course.
