Abstract :
In this letter two different types of FM demodulators, called compound AFC-APC (automatic frequency control--automatic phase control) FM demedulators, have been considered. It is shown that the tracking capability of either of the systems is much higher than that of an ordinary phase-locked demodulator. Experimental results are also presented in support of the conclusions of the analyses.
