Summary This standard specifies the methods of measurement channel sound simulation program. These measurements are only concerned with the audio band; is a measure of the baseband radio-relay system requirements include: TV (Part III). Phone Frequency Division Multiplexing (Part IV), and the mutual interference (Part III Section V) of complement. In fact, the sound channel may be used by the FM subcarrier in the simulation (Appendix A A. 1) or using time division multiplexing technology is digital.
