In the figure we have two circuits of limiters that provide the cut of the negative peaks of a signal. The circuit is from an 80's telecom documentation being adaptable on common receivers.
This precision circuit can provide timings from 0.2 milliseconds to 3 minutes accurately. The...
This circuit uses a phototransistor as sensor. The changes in the resistance of the transistor,...
We found this circuit in 1980s documentation. It can be used independently as CW or by exciting a...
