ABSTRACT
In the year 1847, English mathematician George Boole published The Mathematical Analysis of Logic. This chapter introduces the logic gates that are fundamental building blocks for forming any electronics circuitry. Gates are often called logic circuits because they can be analyzed with Boolean algebra. A timing diagram is a representation of a set of signals in the time domain. It can contain many rows, usually one of them being the clock. It is a tool ubiquitous in digital electronics, which, besides providing an overall description of the timing relationships, helps find and diagnose digital logic problems. The AND gate has only one output but can have two or more input signals. It performs what is known as logical multiplication. All input must be high to get a high output. The AND gate is one of the basic gates that can be combined to form any logic function.
