4.0 Introduction
Sequential Circuits
? The output of circuit depends on the previous output and the
present inputs.
? The inputs must follow a specific sequence to produce a required
output.
? In order to follow a sequence of inputs the circuits must contain
some form of memory to retain knowledge of those inputs, which
have already occurred.
? This memory are obtained by feedback connections, which are
made so that history of the previous inputs is maintained.
? Most sequential systems are based on a small number of simple
sequential circuit elements known as Bistables or Flip Flops.
