This amplifier was found in a 1970s documentation. Darlington transistors can be replaced for modern equivalents of at least 80 V x 2 A, equipped with good heat sinks.
A more efficient filter is the one that diverts the signal to the ground and not only short it, as...
The great advantage of the circuit shown in the figure is that its frequency is controlled by a...
We found this circuit in Texas Instruments' Linear Circuits Applications. It is a peak detector whose...
