1. The 2-bit ripple counter is called as MOD-4 counter and 3-bit ripple counter is called as MOD-8 counter.
2. So in general, an n-bit ripple counter is called as modulo-N counter. Where, MOD number = 2n.

3. There are three types of modulus counter

   • 2-bit up or down (MOD-4)

   • 3-bit up or down (MOD-8)

   • 4-bit up or down (MOD-16)

4. For MOD-16 counter 4 flip-flops are needed.
