Abstract:
A method for determining the period of a repeating pattern of sampled pseudo-random binary sequence generated signals, comprising the steps of:selecting a waveform token having a characteristic such that L=2Nâˆ’1, where L represents the number of bits of said sampled pseudo-random binary sequence, said waveform token being at least N bits long but less than L bits long, and said waveform being non-repeating in a subsequence of L consecutive bits of said of each of said sampled pseudo-random binary sequence generated signals; comparing said waveform token to said sampled pseudo-random binary sequence generated signals to detect occurrence therein; and measuring a repetition rate of said waveform token to determine frequency or phase characteristics of said sampled pseudo-random binary sequence generated signals.
