Continuous wave radio transmission with automatic balancing - emits measuring signals from centre at critical frequency to establish transit time differences

摘要

The continuous wave radio transmission system has a number of transmitters and a configuration which balances the differences in transmit time. Transmission is via cable and at different frequencies. They are linked to a transmission centre. The balance occurs automatically. The transmission centre (CC) emits predetermined measuring signals sequentially to the individual continuous wave radio transmitters (TRM1-n). The measuring signals are at a critical frequency as regards the transmit time differences. The time differences established for all the transmission times are used to set the transit times for the individual radio transmitters. This is achieved by inserting all pass filters.
