    Abstract - (Show below) - (Hide below)

    Gives methods of measurement for the radio frequency parameters required for selective calling to permit measurement of those parameters on receivers that do not have an audio output, specifically for mobile radio receivers having audio frequency band widths (the receiver does not necessarily have an audio output) generally not exceeding 10 kHz for the reception of voice and other types of signals, using angle (Type G or F: phase or frequency) modulation, or double sideband amplitude (Type A) modulation with full carrier, or single sideband amplitude (Type H, J or R) modulation with full, reduced or suppressed carrier. Selective calling is usually used to select one or a group of receivers by conditioning the receiver(s) to deliver a voice message or to activate an alarm.
