Sketch the timing diagram for a 4-bit ripple counter which uses T flip-flops. (See Problem 6.2.25)
Problem 6.2.25
(a) For a JKFF with J K = 11, the output changes on every clock pulse. The change will be coincident with the clock pulse trailing edge and the flip-flop is said to toggle, when T = 1, for the T flip-flop. Show JKFF connected as a T flip-flop and its timing diagram.
(b) Using T flip-flops, show the block diagram for a 3-bit ripple counter and its input and output waveforms.
