The mode of operation of the phase-locked loop is briefly described, an analytical note being given in an Appendix. Communication applications are the tracking receiver, f.m. detection, the phase-locked homodyne and f.s.k. detection. Instrumentation applications are phase modulation, pulse-width modulation, phase-locked servo for magnetic recording and a phase-locked frequency standard. The voltage controlled oscillator, phase detector and loop filter necessary in these applications are discussed.
