This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The ...

This is a simple circuit which helps to change the tune/melody into a different pitch level by devoid of loss in the tune. The circuit, which is presented here, is used to change the tune/melody into ...

I have wanted to make a pulse generator for years. I know you can buy perfectly good ones, but not if you want non-overlapping outputs to drive the mosfets in synchronous-rectified dc-dc converters.

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...
