The invention relates to a low-pass filter for limiting the frequency band of a luminance signal and for delaying said luminance signal, in particular intended for use in the recording channel of a video recording apparatus before the FM modulator. The luminance signal components above a cut-off frequency are attenuated by means of a ceramic filter (11, 31) which is connected to a point of constant potential (earth) and the luminance signal is delayed by means of a delay line (7, 35) arranged in the signal path.
