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:<\/p>\n

    \n
  1. angle modulation [frequency modulation (F3E)\/phase modulation (G3E)], or<\/li>\n
  2. double-sideband amplitude modulation with full carrier (A3E).<\/li>\n<\/ol>\n

    This standard is intended to be used in conjunction with IEC Publication 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.<\/p>\n

    For receivers having audio-frequency band widths generally not exceeding 10 kHz for reception of voice and other types of signal using (a) angle modulation (phase\/frequency modulation), or (b) double-side band amplitude modulation with full carrier.<\/p>\n
