Question: A D FF is sometimes used to delay a binary waveform so that the binary information appears at the output a certain amount of time

A D FF is sometimes used to delay a binary waveform so that the binary information appears at the output a certain amount of time after it appears at the D input.

(a) Determine the Q wave form in Figure , and compare it with the input waveform. Note that it is delayed from the input by one clock period.

(b) How can a delay of two clock periods be obtained?
