With this passive circuit it is possible to modulated in amplitude a low intensity RF signal. The circuit is from old American documentation and uses a germanium diode as its main component.
The purpose of this circuit is to increase the sensitivity of a galvanometer, making it possible to...
We found this configuration in documentation from the 1980s. It applies to almost any operational...
This circuit shows how to use a 12 V regulator to obtain a higher voltage output. The...
