Suggested by Mullard in a1969 documentation, this circuit generates the erasure signal for tape recorders of the time. Transistors can be modern equivalents like BD136 and BD136.
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...
