Title :
Automatic phase adjustment for broadcasting transmitters working in parallel
Abstract :
A digital automatic phase adjustment system which has been successfully used for two short-wave broadcasting transmitters working in parallel in order to increase broadcasting range is described. When the carrier frequency of broadcasting transmitters is changed, the microcomputer will adjust digital phase shifters to ensure the maximum value of composite transmission field intensity, allowing the optimal working state to be established
