Abstract

Signal transmission device by delta modulation of encoded pulses in which encoded pulses derived from an encoded pulse modulator occur in a series of pulses 1 and pulses 0 that vary with the signal characterized by the fact that dynamic signal control is provided a control device that is governed by a level control voltage and a control voltage generator that is fed with the encoded pulses comprising said control voltage generator a detector of polarity alternations characterized in the pulses coded by the occurrence of pairs of pulses 01 to 10 in measurement pulses whose average frequency varies with the degree of control of the code modulator and a frequency detector stage fed by these measurement pulses into a control voltage that varies according to the average frequency of said measurement pulses, said voltage acting of cont roll as a voltage or level control when coupling the output of the frequency detector stage to the input for the level control voltage of the level device.
