This circuit detects when a signal reaches its peak value. The source must be symmetrical and equivalent operational amplifiers can be used. This circuit was found in an old European publication.
We found this circuit in Radio Electronics magazine. It triggers a load (relay) by the noise from...
In this circuit we show how to modulate the pulses produced by a 555 in frequency. The circuit can be...
