The circuit shown in the figure below uses ideal positive edge-triggered synchronous J-K flip flops with outputs X and Y. If the initial state of the output is X =0 and Y =0 just before the arrival of the first clock pulse, the state of the output just before the arrival of the second clock pulse is X=0, Y=0 X=0, Y=1 X=1, Y=0 X=1, Y=1

A synchronous counter using two J-K flip flops that goes through the sequence of states: $Q_1Q_2=00\rightarrow10\rightarrow01\rightarrow11\rightarrow00 \dots$ is required. To achive this, the inputs to the flip flops are $J_1=Q_2,\;\;\;K_1=0\;\;\;\;;\;J_2={Q_1}’, \;\;K_2=Q_1$ $J_1=1,\;\;\;\;\;K_1=1\;\;\;\;\;;\;J_2={Q_1}, \;K_2=Q_1$ $J_1=Q_2,\;\;K_1={Q_2}’\;;\;J_2=1, \;\;\;\;K_2=1$ $J_1={Q_2}’,\;K_1=Q_2\;\;;\;J_2={Q_1}, \;K_2={Q_1}’$

A 2-bit synchronous counter using two $J-K$ flip flops is shown. The expressions for the inputs to the $J-K$ flip flops are also shown in the figure. The output sequence of the counter starting from $Q_1Q_2 = 00$ is $00 \rightarrow 11 \rightarrow 10 \rightarrow 01 \rightarrow 00 …$ $00 \rightarrow 01 \rightarrow 10 \rightarrow 11 \rightarrow 00…$ $00 \rightarrow 01 \rightarrow 11 \rightarrow 10 \rightarrow 00…$ $00 \rightarrow 10 \rightarrow 11 \rightarrow 01 \rightarrow 00 ...$
