This is an old revision of the document!


There are several simple sine/triangle/square wave signal generators, with adjustible peak-to-peak voltage and voltage offset. Frequency range is up to a couple of MHz, but at those frequencies the waveform is less than perfect. Their main use is for audio frequencies circuits and mechantronic circuits.

These are all based around the classic ICL8038, which is effectively a 555 timer with some wave shaping. Consequently the sine waves are noticably distorted at the peaks, and they are unsuitable for serious audiophile purposes.
