ABSTRACT:
A slew rate converter is provided in a video signal recording circuit for limiting a signal having a high frequency and a high amplitude so as to avoid an over-modulation when the signal is reproduced. The high frequency and high amplitude component exceeding a pre-determined amplitude is detected and applied to the slew rate converter for reducing its slew rate so that the signal component having the high frequency and high amplitude is suppressed.
