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 simple circuit for a high impedance magnetic phone (500 ohms or more) has been found in a...
This configuration enables the use of low current switches or sensors to control high power loads...
We found this circuit in the 1993 Motorola Linear Interface ICs. The operational is unusual today, but...
