This circuit is from a 1980's documentation for telecommunications. The circuit is used in SSB and the diodes must be suitable types for the application. The audio input is low impedance.
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...
