Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...
This simple stereo encoder circuit schematic is build with 2 IC MMC4066E and MMC4047 and one transistor BC547B. On IC1 2 and 3 pins is the audio output which is amplified by T1 (current amplification) ...
Even in today’s digital, IT-intensive radio plant, there is still a need to design and build one-of-a-kind electronic circuits. Simple devices such as digital tone generators and small distribution ...
