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 ...

In digital circuits, such as comparators, two 8-bit numbers may be considered to generate and output only when they are the same. Such circuits and those of adders, multipliers, can all be built from basic NAND and NOR gates, they are called combinational logic circuits. Another requirement ...

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). From: Digital Systems Design with FPGAs and CPLDs, 2008 ...
