What is the combinational logic circuit?

The combinational logic circuit is characterized in that the output signal is only a function of the input signal at a certain time, and has nothing to do with the state of transmission at other times. The logic function of combinational logic circuit is derived from a given logic circuit.

The main steps are as follows :

1. The logic circuit is given and the output logic function is determined the logical expression of the output of each gate circuit is written from the output terminal to the output terminal, so that the output of the whole logic circuit is changed logical Function of Quantity. When necessary, it can be simplified, and the simplest output logic function can be obtained.

2. List the truth table to output the state of the variables in a natural binary order of the various values of the combination of generation output logic function, find the corresponding output state, and fill in the table, that is, the truth table.

3. The logic function of the circuit is analyzed by analyzing the characteristics of the truth table.
