Based upon a simple concept, the phenomenon of falselocking is described and the locking range characteristics of a long-loop phase-locked receiver exposed to a signal contaminated with a cochannel interfering tone are presented. Also, the limiting condition of synchronisation in such a situation is obtained.

Inspec keywords: phase-locked loops; signal detection; interference (signal)

Other keywords: locking range characteristics; false-locking; cochannel interfering tone; long-loop phase-lock receivers; synchronisation

Subjects: Signal processing and detection; Electromagnetic compatibility and interference
