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.
