The figure shows how to obtain a pulsating continuous signal from an alternating signal using only one diode. The load resistor depends on the application.
In this circuit of a 1975 publication, a silicon transistor is used as a sensor. We can employ a...
This circuit was found in a 1978 publication. Equivalent operational amplifiers can be used. The...
The great advantage of the circuit shown in the figure is the fact that its frequency is...
