Line 28:

A simple encoder circuit can receive a single active input out of 2^''n'' input lines generate a binary code on ''n'' parallel output lines.

For example a single bit 4 to 2 encoder takes in 4 bits and outputs 2 bits. ProperThe functionillustrated requiresexample thatwill onlysometimes fail as a priority encoder if more than one input line is active at a time.
