An appraisal of some decoding systems for three-gun N.T.S.C. colour television receivers

摘要

Results are given of some practical and theoretical investigations of several types of decoding systems for use with three-gun N.T.S.C. receivers. It is concluded that the (R ???????? Y)/(B ???????? Y) type of decoder is the simplest and most convenient from the point of view of design and adjustment and is likely to be the least critical in operation.
