ABSTRACT:
A system applicable to a digital radio communication system for switching a regular channel and a standby channel includes a demodulator associated with the standby channel. The demodulator has a phase locked loop for clock recovery the band width of which is variable. The band width of the phase lock loop is increased only when a channel switching operation is under way so as to guarantee clock synchronization.
