摘要：
A chrominance signal processing circuit having N (N.gtoreq.2) band-pass filters for dividing a chrominance signal into N regions and N signal processing circuits respectively having different noise eliminating characteristics from each other and each being connected in series to a different one of the N band-pass filters, and means for synthesizing the outputs from the N signal processing circuits to obtain a chrominance signal wherein noise and cross color interference are suppressed.
