Abstract
Sliding Discrete Fourier Transform (SDFT) based phase locking scheme (PLL) is employed to extract the modulation signal from the sinusoidal phase or frequency modulated carrier. Adaptive sampling control based SDFT PLL has been proposed for frequency demodulation. This PLL holds the unique advantage of wider operating range, which has been utilized in the frequency demodulation. Simulation studies prove the efficiency of the demodulation method in retrieving the frequency of modulation signal.
