An apparatus for reproducing from a magnetic tape first and second video signals which are frequency modulated on a carrier, the first video signal having the center frequency of the carrier lower than that of the second video signal is disclosed, which includes a demodulator for demodulating the first and second video signals, a first low-pass filter coupled to the demodulator for filtering the first and second video signals demodulated by the demodulator, the first low-pass filter having a first cut-off frequency, a second low-pass filter coupled to the demodulator for filtering the first and second video signals demodulated by the demodulator, the second low-pass filter having a second cut-off frequency which is lower than the first cut-off frequency, a detector connected prior to the demodulator for detecting whether a reproduced video signal is the first or second video signal and for generating a control signal in response thereto and a switching circuit for selectively supplying the output signal of the first and second low-pass filters to an output terminal in accordance with the control signal from the detector. |
