How many AND gates would be required to completely decode all the states of a MOD- 64 counter and how many inputs must each AND gate have?
A) 128 gates, 5 inputs to each gate
B) 64 gates, 6 inputs to each gate
C) 64 gates, 5 inputs to each gate
D) 128 gates, 6 inputs to each gate

Question

Quizplus · Accepted Answer

A MOD-64 counter has 64 states, so 64 AND gates are needed to decode each state. Each state is represented by a unique 6-bit binary number, so each AND gate must have 6 inputs.
