ABSTRACT:
A signal processing circuit for a signal varying in its properties, e.g., in its degree of distortion, in which the input signal is fed in parallel to two similar processing circuits e.g., equalizers, the characteristic of which can be varied by a control signal, wherein the control signal from the one processing circuit is periodically varied and the output signal is fed to a detector circuit which in optimum signal processing emits a trigger pulse to a holding circuit 52 which stores the corresponding control signal level, which is fed to the second processing circuit.
The detector circuit provided for an optimum equalization is a timing-pulse-controlled integrating circuit with a minimum detector connected at the output side. An application of the circuit for digital data transmission with the related synchronizing timing demodulator and phase control circuits is represented.
