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。-Function Generator according to different purposes, there have three or more of the waveform function generator, a device used in the circuit can be separate devices, can also be integrated device, resulting in square wave, sine wave, triangle wave of the program how species, such as created in the first sine wave, according to the periodic non-sine wave and sine wave which was a function of a certain set, and then by the sine-wave shaping circuit into a square wave, after integrating circuit will turn it into a triangle wave.
