Abstract

Simulcast systems require a linear delay adjust- ment for each transmitter site. This delay adjustment is used to "phase" or synchronize the transmission of the data/audio signal at each site. This delay compensates for the different path lengths from the central site to the remote sites. Both analog and digital equipment is available to transfer the audio/data signals from the central site to the remote sites. Microwave systems are the most common form of the distribution network between the central sites and the remote sites. Leased lines from the phone company are another alternative.
