Abstract
A decoding system having a clock recovery system for maintaining the optimum time for sampling a signal. The clock recovery system is particularly useful in decoding 1 Mbps signals for two-level Gaussian frequency shift key (GFSK) modulation and 2 Mbps signals for four-level Gaussian frequency shift key (GFSK) modulation. The clock recovery system remains reliable with temperature variations, and maintains a stable frequency independent of data pattern.
