Assuming that all flip-flops are in reset condition initially, the count sequence observed at Q_A in the circuit shown is

The given figure shows a ripple counter using positive edge triggered flip-flops. If the present state of counter is Q₂ Q₁ Q₀ = 011, then its next state ( Q₂ Q₁ Q₀ ) will be

The present output Q_n of an edge triggered JK flip-flop is logic 0. If J=1, then Q_n+1

A master slave flip-flop has the characteristic that
