ABSTRACT:
An improved synchronization system for use with simulcast transmission systems is described. The invention provides a method and means for keeping the information signals for adjacent transmitters in the system in synchronization. This invention utilizes a centrally located master transmitter and control unit and a plurality of secondary transmitters disposed in an annular fashion around the master transmitter. In operation, the innermost annular band is synchronized to the master transmitter, while the remainder of the system is disabled. The next adjacent annular band is then synchronized to the innermost annular ring. The process is repeated until every annular band in the system is synchronized.
