Question

A SISO shift register may be used to introduce time delay ∆t=200 ns in digital signals.Assume this shift registers is manufactured by N number of D flip-flops having clock frequency 50Mhz.The required value of N is

Answer 1

200ns= N * (1/50*10^6)

So N=10

Total delay = no of D flipflops * time period of each .
