Components of Sequential Circuits

Sequential switching circuits are composed of combinational circuits and memory elements.

Past History in Sequential Circuits

Memory elements store past information, like past outputs, making the circuit's future dependent on its history.

Shift Register

Shift registers are a type of sequential circuit that can shift data by moving bits one position at a time.

Sequential Generators

Sequential generators in sequential circuits use SR latches and flip-flops to create specific output patterns.
