TRANSMITTER PROVIDED WITH MODULATION SIGNAL DELAY CIRCUIT

摘要

PURPOSE:To attain communication without interruption of head or tail of speech by retarding a time of a modulation input of a transmtter reaching a modulator by a time corresponding to the leading time of the transmitter. CONSTITUTION:A delay circuit D is inserted between a low frequency amplifier AFAMP and a modulator MOD to retard a modulation signal and a timer circuit TIM to hold the transmission function by a delay time of the modulation signal at the end of call is connected to a voice control VOK. Since a switching circuit is kept in contact state with the timer circuit TIM by a prescribed time from the time when a modulation signal fa not subject to any delay is lost at the end of call, the transmitter is brought into the operating state during that time.
