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 ...

The Stereo Field is an intriguing box of synthesized tricks which contains mirrored stereo circuits that are manipulated through touch. When a player's skin touches plates on the upper surface, points ...

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 ...

Over the past 20 years, the audio services that telcos supply to broadcasters have migrated from balanced analog copper circuits to digital solutions based on synchronous E1 and T1 networks. The next ...

In radio circuits their extremely narrow bandwidth means they can be daisy-chained to make an extremely selective filter. One method of generating a single-sideband transmission makes use of a crystal ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...
