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 ...

When we build an electronic project in 2016, the chances are that the active components will be integrated circuits containing an extremely large amount of functionality in a small space. Where onc… ...

FM Receiver Circuit Schematic The coil details are presented in the fm receiver circuit diagram. The radio receiver is adjusted on different stations with the help of C5. P1 potentiometer is adjusted ...

If you’ve never heard of “Manhattan Style” circuit construction, you’re not alone. Popular in ham radio circles, the process looks nicer than straight dead bug style circuit building, but ...

Graphene transistors are attractive for many applications but making integrated circuits without degrading their characteristics is proving challenging. Here, the authors demonstrate a radio ...

VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a constant inductance that the use, some years ago, of variable inductances or variometers with fixed ...

Initial evidence is found that the brain has a 'tuning knob' that is actually influencing behavior. Brain circuits can tune into the frequency of other brain parts relevant at the time.

A self-organising electronic circuit has stunned engineers by turning itself into a radio receiver. What should have been an oscillator became a radio This accidental reinvention of the radio ...

Wireless communications require radio frequency (RF) systems to transmit and receive radio signals, making both transmitters and receivers vital for e ...
