Q1:

For a Mod-64 synchronous counter the number of flip flops and AND gates needed is

A 6 and 4 respectively

B 4 and 6 respectively

C 7 and 5 respectively

D 5 and 7 respectively

ANS:A - 6 and 4 respectively

26 = 64 Hence 6 flip-flops. The number of AND gates is 6 - 2 = 4 see in the given figure
