Q. 34 A synchronous counter using two J - K flip flops that goes through the sequence of states: $Q_{1} Q_{2}=00 \rightarrow 10 \rightarrow 01 \rightarrow 11 \rightarrow 00 \ldots$ is required. To achieve this, the inputs to the flip flops are:
Clock
(a) $J_{1}=Q_{2}, K_{1}=0 ; J_{2}=Q_{1}^{\prime}, K_{2}=Q_{1}$
(b) $J_{1}=1, K_{1}=1 ; J_{2}=Q_{1}, K_{2}=Q_{1}$
(c) $J_{1}=Q_{2}, K_{1}=Q_{2}^{\prime} ; J_{2}=1, K_{2}=1$
(a) $J_{1}=Q_{2}, K_{1}=Q_{2}, J_{2}=Q_{1}, K_{2}=Q_{i}^{\prime}$
