Chapter 7 Counters and Registers

Chapter 7 Counters and Registers. 7-1 Asynchronous(ripple)counters. Asychronous Counters(Cont.). Each FF output drives the CLK input of the next FF. FFs do not change states in exact synchronism with the applied clock pulses. There is delay between the responses of successive FFS.
