WebValues of RSE for ACSB and FM systems are calculated using the measured values of co-channel protection. It is found that 5 kHz ACSB systems appear to be about 1.5 to 8.4 times more efficient than 25 kHz FM systems. The large variation arises mainly from the differences in measurement techniques and criteria which tends to hide the real ...
