*Sign up*Introduction
•
A digital “Sequential Circuit” is one that consists of one or more
Latches or Flip Flops controlled by a “clock signal” (clock pulse).
•
We have already simulated a couple of very simple such circuits.
•
Today we will look at a step by step analysis of a sequential circuit.
•
We will do this by considering an example.
