Abstract
A method for frequency acquisition comprising steps of, acquiring samples of an input signal, each sample having edges, making sets with a fixed number of consecutively taken samples, numbering the edges in each set and determining a number of edges, comparing the number of edges in each set with an expected number of edges in the sets, increasing a frequency of a reference oscillator used in acquiring samples if the actual number of edges exceeds the expected number of edges, and decreasing the frequency of the reference oscillator used in acquiring samples if the expected number of edges exceeds the actual number of edges in a set.
