Abstract
PURPOSE: To obtain a drop-out compensating system which approximately doubles the output signal amplitude of delay line in the signal missing period to the signal wherein the input signal of the delay line includes output signal by constituting a comb type filter by the use of the delay line and adder.
CONSTITUTION: The magnetic video recorder-reproducer is formed by a carrier chrominance signal input terminal 18, switch circuit 19, IH delay line 20, amplifiers 21, 22 (provided that the amplification factor of 22 is twice that of 21), switch circuit 23, adder 24, inverter 25, carrier chrominance signal output terminal 26 and the input terminal 27 of the pulse obtained by detecting the drop-out. The comb- type filter is constituted by the delay line 20 and adder 24 and the output signal amplitude of the delay line 20 is approximately doubled by the amplifier 22 in the missing time of the reproduction signal. At the same time, the signal being inputted to the delay line 20 is made the signal including at least the output signal of the delay line 20.
