ABSTRACT:
A system and method for squelching noise and storing messages. Many receiving systems produce noise bursts at the end of the reception of a message and prior to the operation of the muting circuit. Such noise bursts are especially severe in frequency modulation systems using limiters. By delaying the audio signal until the squelch circuit's hang time is completed the noise bursts are muted.
One application of this invention is in vehicles such as police cars and taxicabs. For such an application one of the essential parts of almost every message is the street address where the vehicle is needed. Since it is easy to confuse addresses, and thereby require a repeat of the message, a recording of at least the address portion of the message would be most useful. A storage system is provided in order to allow the repetition of messages.
