摘要:
A fast algorithm for measuring the frequency shift and phase jitter of telephone data channels which uses simple methods for extracting and processing the phase information of a received test signal was described in Part 1. A detailed analysis is now carried out for the Hilbert transformer and phase filter. The Hilbert transformer requires only one delay element, and two additions for each signal sample, and is thus attractive for general phase extraction applications with sinusoidal signals.
