CHAPTER 6 Logic Gates
6.1 THE AND GATE
An AND gate has two or more inputs but only one output. AND gate is also called an all or nothing gate.
Bellow figure shows symbols and truth tables of two-input and their input AND gates. Note that the output is 1 only when each one of the inputs is 1. The symbol for the AND operation is .or we use symbol at all. The AND operation is logical multiplication.
6.1 (a) Two-input AND gate
With the input variables to the AND gate represented by, A, B, C...., the Boolean expression for the output can be written as X = A.B and lead as “X is equals to A and B”.
