Abstract

Regulator system of the audio pass band for receivers of hertzian waves, essentially characterized in that it comprises an audio-frequency filter, of the type of low pass with a cut-off frequency corresponding to the upper limit of the pass band of the receiver, connected to the the detector's output and that it delivers its throughput to the audio frequency circuits; means for varying, within certain limits, the cutoff frequency of the filter; sensor means of the signal level received at all times, and a control circuit that applies a function corresponding to this signal level to the variator means of the cutoff frequency, in the sense that it is reduced as the frequency decreases. Level of said received signal. (Machine-translation by Google Translate, not legally binding)
