Abstract
A dynamic modification algorithm of the conventional digital phase-locked loop (CDPLL) design parameters is proposed to get a modified DPLL (MDPLL) which has nearly symmetric two-sided acquisition range. With the help of extensive simulation results, it is established that in comparison to a CDPLL, the MDPLL has larger acquisition range and better FM demodulation capability. The performance degradation due to additive noise is more pronounced in the case of an MDPLL
