Sequential logic circuits are based on combinational logic circuit elements (AND, OR, etc.) working alongside sequential circuit elements (latches and flip-flops that will be grouped together to form registers).
Examples of Sequential Logic Circuits The examples of sequential logic circuits are discussed below. Clocks State changes of most sequential circuits occur at times specified by free-running clock signals. As the name implies, sequential logic circuits require a means by which events can be sequenced...
A sequential circuit consists of logic gates and flip-flops. A flip-flop (ff) is a bistable device that has two outputs. One output indicates the true variable of the output, and the other indicates its complement. Such a device is used to store one bit of information. In concept, a ...

Synchronous sequential circuits This type of system uses storage elements called flip-flops that are employed to change their binary value only at discrete instants of time. Synchronous sequential circuits use logic gates and flip-flop storage devices. Sequential circuits have a clock signal as one...
