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.
We found this circuit in an old Popular Electronics. The circuit can be applied to other...
With this circuit it is possible to receive the signals from the 11-meter band (27 MHz) in a...
We found this circuit in an American publication from the 90s. The transistors must be provided with...
