摘要：函数信号发生器根据用途不同，有产生三种或多种波形的函数发生器，其电路中使用的器件可以是分离器件，也可以是集成器件，产生方波、正弦波、三角波的方案有多种，如先产生正弦波，根据周期性的非正弦波与正弦波所呈现的某种确定的函数关系，再通过整形电路将正弦波转化为方波，经过积分电路后将其变为三角波。也可以先产生三角波-方波，再将三角波或方波转化为正弦波。随着电子技术的快速发展，新材料新器件层出不穷，开发新款式函数信号发生器，器件的可选择性大幅增加，所以，可选择的方案多种多样，技术上是可行的。

Abstract：Function signal generator according to different purposes, there have three or more of the waveform function generator, the circuits used in the device can be separated from the device, and can also be integrated device, generates square wave, sine wave, triangle wave solutions are various, such as the first generated sine wave, according to the periodic non sine wave and sine wave show a determined by function, and through the shaping circuit will be transformed into square wave sine wave, after integral circuit after converting it into a triangle wave. Can also be created in the first triangular wave square wave, triangle wave and square wave can be transformed into a sine wave. With the rapid development of electronic technology, new material and new devices emerge in an endless stream, the development of new type function signal generator, device optional increase substantially, so, can choose the scheme is varied, it is technically feasible.
