Sequential Logic Gates. The sequential logic circuit also involves memory elements along with the logic gates. Sr flip flop is a memory device and a binary data of 1 bit can be stored in it.
It is then called a sequential logic system since its output can be influenced by its previous state s i e. Such things as flip flops counters registers decoders and memory devices are included in this classification. These devices play a unique role in the operation of a digital system.
Thus the output generated by the sequential circuit depends not only on the present state of the input but also on the previous outputs.
Flip flop is a sequential circuit which generally samples its inputs and changes its outputs only at particular instants of time and not continuously. When using any of these gate setups the overall system has memory. Sr flip flop has two stable states in which it can store data in the form of either binary zero or binary one.
