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.
In this configuration shown when triggered by a transition from high to low level on pin 2, the...
We found this circuit in an old operational amplifier manual. The operational amplifier can be of...
This interesting circuit for the RDA8851 allows you to obtain two volumes with a simple touch. The...
