摘要：函數信號發生器根據用途不同，有產生三種或多種波形的函數發生器，其電路中使用的器件可以是分離器件，也可以是集成器件，產生方波、正弦波、三角波的方案有多種，如先產生正弦波，根據周期性的非正弦波與正弦波所呈現的某種確定的函數關系，再通過整形電路將正弦波轉化為方波，經過積分電路后將其變為三角波。也可以先產生三角波-方波，再將三角波或方波轉化為正弦波。隨著電子技術的快速發展，新材料新器件層出不窮，開發新款式函數信號發生器，器件的可選擇性大幅增加，所以，可選擇的方案多種多樣，技術上是可行的。

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.

Key words: waveform; function generator；square wave； sine wave； triangle wave
