A Definitive Guide to Logic Circuits and Advanced Circuits

Introduction

The Aims and Objectives of the Book

My main aim in writing this book is to introduce you to the exciting and challenging field of digital electronics. I want to develop your desire and ability to understand how digital circuits work.

After reading this book, you should be able to do some or all of the following:

• You will understand what TTL and CMOS mean and appreciate their main differences.

• You should know what the five main logic gates are and their respective symbols and Boolean expressions.

• You should know the basics of Boolean algebra and use it to simplify logic expressions and circuits.

• You should know what Karnaugh maps are and how to use them to simplify logic circuits and expressions.

• You should know how to implement the 1st and 2nd canonical formats for Karnaugh maps.

• You will know how the JK flip flop works and how it was born out of the SR latch.

• You should be able to use the JK flip flop and the D-type latch to create a series of counters and different shift registers such as SIPO, SISO, PIPO, and PISO.

• You should understand the difference between sequential and combinational logic.

• You should be able to use a range of design techniques, that is, state diagrams, transition tables, etc.

• You should be able to create a range of combinational logic circuits such as half and full adders, binary subtractors, multiplexers, etc.

• You should understand how the 555-timer IC works and how to configure it in a range of different applications such as the monostable, the astable, and PWM.

• You should be able to design a range of logic circuits.

• You should be able to use the ECAD software TINA 12.
