Abstract

PURPOSE: To increase the picture quality through the elimination of sprious, by making suitable frequency offset to multiplexed carriers in TV signal multiplex broadcast sets.
CONSTITUTION: Carriers f1 to f7 are offset from the specified 12MHz distance by respectively +5k or -5kHz. Further, the improvement for mutual interference by about 15 dB can be obtained by obtaining the difference of each carrier to 2/3 and 4/3 of the horizontal synchronizing frequency to interference 2 waves.
