Abstract
A type of digital phase-locked loop (DPLL) with an AND-filter instead of a random walk filter (RWF) is proposed in order to increase phase acquisition speed. This loop is compared with conventional loops. It is found that the phase acquisition speed of this proposed loop is better than that of either of the conventional loops with the same noise suppression effect. Performance is verified by computer simulation
