Explain Mod-3 Counter with circuit diagram and truth table

Jyoti Pant · Accepted Answer

A counter has a natural count of $2^{n}$ where n is the number of flip flops in the counter Counter of modulus of 3 is Mod-3 counter

From the above diagram and truth table,we see that after two clock pulses $Q_{0}$ is low(0) and $Q_{1}$ is high (1) $\bar{Q_{1}}$ is fed back to $J_{0}$ If $Q_{1}$ =high (1) then $\bar{Q_{1}}$ =low(0)=> $J_{0}$ =0, $K_{0}$ =1 At the third clock pulse the first flip flop will remain in the reset state $Q_{0}$ will remain zero here $J_{1} = 0$ , $K_{1}$ =1,second flip flop will also remain in reset state => $Q_{1}$ =0 Since $\bar{Q_{1}}$ is fed back to $J_{0}$ ,the counter resets to 0 0 after three clock pulses
