Abstract

PURPOSE:To improve S/N remarkably by using a high-pass filter between the FM detector and integrator of an FM detection system which performs FM detection and integration. CONSTITUTION:An intermediate frequency signal is applied 3, which eliminates the amplitude-modulated component of the main signal, and then applied to FM detector 4. Since the output of detector 4 contains subsignal (L-R) and a detection component which corresponds to a pilot signal, high-pass filter 5 removes the detection component of the pilot signal and its output is supplied to integrator 6. Integrator 6 detects the subsignal, which is sent to matrix circuit 2 via monaural/stereo change- over switch 7.
