Description

This paper carries the analysis of crosstalk from sub-channel to main-channel of the multiplex-sound television receivers by theoretically examining the relationships between the crosstalk components and the various characteristics of the receiver circuits and reveals the mechanism of development of this crosstalk.<BR>The authors point out that the above crosstalk is produced mainly as the nonlinear phase and amplitude distortion products of the sub-channel signal and the buzz and buzz beat components in the sound signal.<BR>It is confirmed that the experimental results agree qulitatively with the theoretical analysis and the means to reduce the crosstalk are proposed.
