Counters - Technical MCQs

Q1:

A 22-MHz clock signal is put into a MOD-16 counter. What is the frequency of the Q output of each stage of the counter?

A Q1 = 22 MHz, Q2 = 11 MHz, Q3 = 5.5 MHz, Q4 = 2.75 MHz

B Q1 = 11 MHz, Q2 = 5.5 MHz, Q3 = 2.75 MHz, Q4 = 1.375 MHz

C Q1 = 11 MHz, Q2 = 11 MHz, Q3 = 11 MHz, Q4 = 11 MHz

D Q1 = 22 MHz, Q2 = 22 MHz, Q3 = 22 MHz, Q4 = 22 MHz

ANS:B - Q1 = 11 MHz, Q2 = 5.5 MHz, Q3 = 2.75 MHz, Q4 = 1.375 MHz

4ff are used 2^4 = 16 {output of each ff is equal to f/2,f/4,f/8,f/16}

So f=22Mhz. [11,5.5,2.75,1.375].
