原文 Logic Circuits
An electronic gate is a subunit that allows a signal to pass under certain conditions. If these conditions are not satisfied the gate remains closed and the signal cannot proceed. The dictionary defines the word "logic" as a "connection or outcome of events" and it is in this sense that the word is applied to electronic gates. The connection of events being that if certain conditions are satisfied
(that is, if certain events take place) , then a further event follows logically. The field of logic in electronic systems is very broad and logic theory is being applied more and more to all kinds of control, measurement and calculating system, Logic theory is, of course, the basis of what is probably the best known electronic system, the digital computer.
Logic circuit in general comes under a branch of electronics known as digital applications as opposed to linear or analogue applications. Digital systems use signals, which are of pulse form, that is, a series of short-duration square waves. Analogue systems use signals of, or derived from, the familiar sine waveform. Amplifiers used in digital systems must be wide-band amplifiers because of the many harmonics that make up a square wave.
