If you have a cheap function generator it’s likely to contain a one-chip solution that generates approximations to sine and triangle waveforms through modifying a square wave with a set of filters.

High frequency waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can modify the circuit to generate triangle or square ...

Following is a couple of random snaps from my workbench taken while I was building the function generator, a $10 do it yourself ... Here’s a pointer to generate 1MHz sine wave (and square wave) in a ...
