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.

一个电子门是一个亚基，它允许信号通过一定的条件。如果这些条件得不到满足的大门仍然关闭和信号无法继续。这本词典定义为“连接或活动的结果“字“逻辑“，并在这一词应用到电子门感。因为，作为一个事件的连接，如果某些条件得到满足
（也就是说，如果某些事件的发生），然后再事件如下逻辑。在电子系统的逻辑领域非常广泛，逻辑理论被应用到越来越多的控制，测量和计算系统中的所有种，逻辑理论，当然，什么可能是最知名的电子系统，基础数字计算机。
一般的逻辑电路来作为下一个，而不是线性或模拟应用数字应用知名电子科。使用数字系统的信号，这是脉冲形式，就是一种短期方波系列。使用模拟信号系统，或从熟悉的正弦波形而得。在数字系统中使用的放大器必须是因为构成方波多谐波宽带放大器。
