Draw the timing diagrams for the output of z. PARTS 3A & 3B

Consider the four D flip-flops connected in series shown in the figure below. The initial values of the flip-flops are shown at the output of the flip-flops and the input is fixed at '1' Draw the output waveform z, of a J-K flip-flop with asynchronous clear given the waveform of Cir, J. and K inputs. Assume z is initially 0. The state table of J-K flip-flop is
