In this paper, the authors present optimized implementation of Digital Phase Locked Loops (DPLLs) for generating RF carrier signal used for phase demodulation. The method used for designing DPLL is based on linear control theory and the receiver is phase locked at higher radio frequency signal which is highly noisy. The building blocks of DPLL such as loop filter are implemented with a new method in digital domain for better noise rejection and accuracy. The paper aims to offer aided acquisition of RF signal with fast frequency and phase locking.
