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 ...

Most of my Blog posts involve short 3-4 hour projects/hacks that I just build up for learning and fun. I thought it was time to develop something a bit more involved and share my design process in a ...

If these signals exhibit a simple, periodic waveform, such as with sine, square, or triangular waves, the generators are called function generators. They are often used to check the function of ...

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 ...

On its own, your computer can't make a sound. Digital data from audio and video files needs to be turned into something that our ears can hear, and this requires specialized hardware and sophisticated ...
