Methods of measurement for equipment used in terrestrial radio-relay systems - Part 3: Simulated systems - Section Six: Measurements for sound programme transmission
地面无线电中继系统中使用的设备的测量方法 - 第3部分:模拟系统 - 第6节:声音节目传输的测量
Deals with methods of measurement for sound-programme analogue channels carried by radio-relay systems. Concerned only with the audio-frequency band and is additional to the measurement described in sections three, four and five of this publication. Sound channels can be derived using analogue or time division multiplex techniques.
