Normally in a wide-area private land mobile system, the voice users are "polite"-only one user talks at a time. However, occasionally multiple users will key up and begin talking at roughly the same time. Existing analog comparators, whose job is best signal selection, do not realize that they are dealing with more than one signal source, let alone more than one copy of a signal. Because compara- tors will switch signals as signal qualities change, the result in this situation is that it may altogether change which user's audio gets routed.
