Question

1) Explain 4 bit mod-16 binary counter with timing diagram​

Answer 1

Answer:

For example, a 2-bit counter that counts from 002 to 112 in binary, that is 0 to 3 in decimal, has a modulus value of 4 ( 00 → 1 → 10 → 11, and return back to 00 ) so would therefore be called a modulo-4, or mod-4, counter. Note also that it has taken four clock pulses to get from 00 to 11.Asynchronous Counters use flip-flops which are serially connected together so that the input clock pulse appears to ripple through the counter. An Asynchronous counter can have 2n-1 possible counting states e.g. MOD-16 for a 4-bit counter, (0-15) making it ideal for use in Frequency Division applications.
