A test signal generator is invaluable when making or repairing electronic equipment. Although a fully-fledged, accurate (and expensive!) sig gen is desirable, there are many occasions when a simple, non-calibrated, highly portable signal source will suffice for a quick test such as signal tracing. To that end I've designed this circuit which selectively generates square, triangle and pseudo-sine waves in three frequency ranges covering 15Hz to 2MHz.
The core of the generator is a...
