DIN IEC 60107-4-2000 电视广播接收机推荐测量方法.第4部分:双载波调频装置多声道电视接收机电气测量
Recommended methods of measurement on receivers for television broadcast transmissions - Part 4: Electrical measurements on multichannel sound television receivers using the two-carrier FM-system (IEC 60107-4:1988 + A1:1999)
The methods of measurement for the important electrical characteristics of receivers described in this standard apply to television receivers designed for the reception of television broadcast transmission using the two-carrier FM-system. The two-carrier system offers the possibility of audio-transmission using three different modes of operation: dual-sound: transmission of two independed sound-signals, stereophonic: transmission of left and right channel sound signal and monaural: transmission of a monaural signal.#,,#
