CIRCUIT-ARRANGEMENT FOR THE EQUALIZATION OF THE BASE-BAND INTERMODULATION SPECTRUM IN FM RADIO-CHANNELS

摘要

Circuit-arrangement for the equalization of the base-band intermodulation spectrum in FM radio-channels, characterized by comprising an input and an output, said output being connected to the input of a circuit (N) having a non-linear (n+1)th characteristic and to one of the inputs (1) of a summing circuit (S), the output of said non-linear circuit being connected to the input of a differenciator (D) having an output connected to the input of a controllable amplifier (A) which has an output connected to the other input of the summing circuit (S) whose output defines the output of said circuit arrangement.
