<p>SIMULCAST TRANSMISSION SYSTEM A system of the type wherein transmissions of the same information are simultaneously broadcast by spatially removed transmitter sites. A control center establishes transmission links to the transmitter sites. The center includes electronic storage for determining the required time delay for each signal applied over a predetermined link to assure phase coherency of overlapping transmissions. Upon the establishment of a new link the appropriate time delay is recalled from memory and used to program a bucket brigade to thereby provide the required delay to signals carried over the link.</p> |
