This circuit is from a 1980s Signetics documentation. The circuit separates the modulation signal from a carrier. The used components are not common today.
Using 18 or 24 MHz crystals, this circuit is intended for producing reference signals with...
This circuit can source 3 to 12 V with currents up to 500 mA depending only on the transformer....
Another alternate action switch that uses a NAND Schmitt Gate [4093 IC] is shown here. The...
