Abstract
Electronic apparatus for receiving amplitude or frequency modulated facsimile signals detects the instantaneous value ( i.e., the amplitude or frequency) of the modulation by a circuit including means detecting the modulation value in each cycle of the signal and producing a gating signal corresponding in duration to the detected modulation value, a generator of clock pulses higher in frequency than the signal, and a modulator responsive to the clock pulse and gating signal to pass a number of clock pulses commensurate with the modulation value to a counter which generates a marking signal commensurate in amplitude to the modulation value for application to a facsimile recorder.
