Question

What type of signal does each logic gate produce? (Digital signal/analog signal)

Answer 1

A digital circuit is typically constructed from small electronic circuits called logic gates that can be used to create combinational logic. Each logic gate is designed to perform a function of boolean logic when acting on logic signals. All digital circuits operate using digital, discrete signals since analog circuits are very difficult to design due to the fact that they are very susceptible to noise and small changes in the voltage level of an analog signal may produce significant errors when being processed. In logic systems, variables, circuits, statements, etc., can be treated in one of two distinct states: true or false, yes or no, on or off, present or absent, energized or not energized, conducting or non-conducting, high voltage or low voltage, and so on.
