# BUFFER GATE

## BLOCK DIAGRAM OF BUFFER GATE

A Buffer gate does not produce any particular logic function since the binary value of the output is the same as the binary value of the output. This circuit is used merely for power amplification. For example, a buffer that uses 3 volts for binary 1 will produce an output of 3 volts when its input is 3 volts. However, the amount of electrical power needed at the input of the buffer is much less than the power produced at the output of the buffer. The main purpose of the buffer is to drive other gates that require a large amount of power. The output equation of buffer gate is Y = A where Y is the output to the circuit and A is input to the circuit.

## TRUTH TABLE OF BUFFER GATE

The Truth table shown below. when input is 0 then output is also 0 and when input is 1 then output is also 1.
