Patent ID: 7068989

Claim:
A communication equipment comprising a transmitting part for transmitting transmission information by using an output signal of a phase lock oscillator which has a phase-locked loop including a reactive element and whose oscillation frequency varies according to an input signal, wherein said phase lock oscillator comprises: a limit discriminating section for discriminating an instant preceding an instant which is a limit that said phase-locked loop is capable of maintaining its lock state; and a controlling part for starting a processing of varying a reactance of said reactive element at a first instant succeeding said preceding instant, when said preceding instant is detected by said limit discriminating section, in which said controlling part controls said transmitting part to transmit said transmission information at a higher transmission rate than a transmission rate applied immediately before said preceding instant, the transmission being performed: during a specified period from an instant at which said preceding instant is detected, to said first instant; or after a predetermined time elapses from said first instant.
