适用范围

This section deals with baseband-to-baseband measurements of the noise performance of simulated radio-relay systems used for frequency division multiplex (f.d.m.) telephony. These measurements are signal-related and are additional to those already given in Part 3, Section Two of this publication, Measurements in the Baseband, which are common to telephony, television and sound programme transmission.
