SECTION ONE – GENERAL
1 Scope
Replace the text of this clause by the following:
This standard refers specifically to mobile radio receivers having audio-frequency bandwidths
generally not exceeding 10 kHz for the reception of voice and other types of signals, using:
a) angle modulation (frequency modulation (F3E)/phase modulation (G3E)), or
b) double-sideband amplitude modulation with full carrier (A3E).
This standard is intended to be used in conjunction with IEC 60489-1. The supplementary
terms and definitions and the conditions of measurement set forth in this standard are intended
for type tests and may also be used for acceptance tests.

5.10.1 Limitation of the audio-frequency band
Replace the text of this subclause by the following:
Because some properties, for example noise and audio-frequency harmonic distortion, depend
upon the audio-frequency bandwidth, reproducible results can be obtained only when the band
of audio-frequencies occupied by the demodulated signal is restricted to specified limits.
This restriction may be accomplished by means of a band-limiting filter preceding any audio-
frequency measuring device and adapted to the type of signals to be transmitted. The filter may
be incorporated within the measuring equipment. When measuring residual hum and noise,
only the low-pass portion of the filter should be specified.
In the case of speech transmission, the filter shall be in accordance with the psophometric filter
described in ITU-T Recommendation O.4
