ABSTRACT:
A circuit for processing an angle modulated signal having amplitude modulation signal components in stereophonic broadcasting systems. An inverse modulation of a signal to be detected is provided over a first signal amplitude range, and a constant signal level is provided over a remaining range for signals having a marginal amplitude level. The discontinuity in the control range avoids noise expansion for high negative amplitude modulator levels for the signal to be angle modulated.
