Instead of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less ...

A simple AM transistor radio can be made with surprisingly few components, but for a circuit with a reasonable ... and two for the audio power amplifier, but it’s possible we’re not factoring ...

Each project consists of a useful practical circuit that is demonstrated with a neatly fabricated PCB. The design details including the Gerber file is available for download to provide a complete ...

As a result, designing transistor amplifier circuits gives me pause to this day. Not long after I graduated in 1985, I heard that half of the network analyzer was thrown away in order to save space.

Problem solved. Most multimedia setups can be handled easily by a single 15-amp circuit. Powering connected equipment from the same AC socket will eliminate most ground loops. If you still get hum ...
