ABSTRACT:
A recording and reproducing apparatus which can prevent deterioration of the picture quality from being caused by an overshoot, a ringing or a noise component when, using a video tape recorder which can process two kinds of video signals having different aspect ratios, a video signal having a greater one of the aspect ratios is reflected on a television set. The recording and reproducing apparatus comprises a peaking circuit for adding an overshoot or a ringing to a video signal, a noise canceller circuit for cancelling noise from the video signal and a comb line filter for removing noise from the video signal. The peaking circuit, the noise canceller circuit and the comb line filter are capable of changing over the peaking frequency, the noise cancelling characteristic and the comb line filter characteristic thereof, respectively, in accordance with an aspect ratio of the video signal.
