The simplest one transistor audio mixer circuit diagram on the net. It has only one transistor and can support as many audio signal as you can afford. BC109C is a very cheap transistor and with a few ...

This single transistor audio mixer is used in an amplifier circuit design with base driven transistor and with its emitter being current controlled, most of the driving current flows through the ...

Wireless communications took a small leap forward today with the announcement that researchers have created a functional integrated circuit smaller than a grain of salt. The circuit is a broadband ...
