how is it possible to make a module 2n counter

Question

How is it possible to make a module 2ⁿ counter using N-flipflops?  Name the two types of such counters.

Ans:

Module 2ⁿ counter counts total 2ⁿ distinguishable states we identify that n-bit can shows 2ⁿ unique combinations for example: Mod-8 counter will count net 8 states and as 8=(2³) each state will have combination of 3 bits.

Two kinds of such counters are:

• Mod 8 counter
• Mod 16 counter
