This circuit was obtained from an 80's Radio Electronics. The circuit decodes “scrambled” or sinusoidal encoded signals by providing an audio signal at the output.
Standing wave ratio or SWR is an important measure of whether all power from a transmitter is being...
Here we show how to add a reset key to the monostable using two NAND gates (CB127E). When the key...
This short-range circuit can act as a wireless microphone. We got the schematic and the printed...
