System for reducing or suppressing noise components in television signal

摘要

A system for reducing or suppressing the noise components in the TV signal wherein the component representative of the difference between the as-input (or as-received) TV signal and the TV signal which has been delayed by one horizontal scanning period is derived, the difference component is subjected to the amplitude limitation, and the noise components in the TV signal reproduced by VTR or the like are removed or suppressed by a comb filter comprising said as-input TV signal and the amplitude-limited difference component.
