The current state $${Q_A}{Q_B}$$ of a two $$JK$$ flip-flop system is $$00.$$ Assume that the clock rise-time is much smaller than the delay of the $$JK$$ flip-flop. The next state of the system is

The figure shows a digital circuit constructed using negative edge triggered $$J-K$$ flip flops. Assume a starting state of $${Q_2}\,{Q_1}\,{Q_0} = 000.$$ This state $${Q_2}\,{Q_1}\,{Q_0} = 000$$ will repeat after _____ number of cycles of the clock $$CLK.$$

In the following sequential circuit, the initial state (before the first clock pulse) of the circuit is $${Q_1}{Q_0}$$ $$=00.$$ The state $$\left( {{Q_1}{Q_0}} \right),$$ immediately after the $${333^{rd}}$$ clock pulse is

A $$JK$$ flip flop can be implemented by $$T$$ flip flops. Identify the correct implementation.
