Device for demodulating a frequencymodulated signal

In order to reduce disturbances in a device for demodulating a frequency-modulated signal, which disturbances are cuased by head-switching in a video recorder, the low-pass filter which is normally arranged between the demodulator (10) and the hold circuit (12) is transferred. The low-pass filter (2...

Beschreibung
Zusammenfassung:	In order to reduce disturbances in a device for demodulating a frequency-modulated signal, which disturbances are cuased by head-switching in a video recorder, the low-pass filter which is normally arranged between the demodulator (10) and the hold circuit (12) is transferred. The low-pass filter (23, 24), i.e. at least the capacitive element (24) of this filter, is arranged in the hold circuit (12), at least the capacitive element (24) of the low-pass filter (23, 24) being arranged in the main signal path after the switching means (18).
