Sequential Logic
Description
Along with combinational logic, sequential logic is a fundamental building block of digital electronics. The output values of sequential logic depend not only on the current input values (i.e., combinational logic), but also on previous output values. Thus, sequential logic requires a clock signal to control sequencing and memory and to retain previous outputs. In this activity we will use the D flip-flop. We are limiting our use to this type of flip-flop in this introductory unit because of its simplicity and ease of use. The D flip-flop is just one of many different types of flip-flops that can be used to implement sequential logic circuits.
