Fourier analysis of phase-shifting algorithms

摘要

Abstract: The analysis of phase detection algorithms in the Fourier domain provides information about the overall performance characteristics for complex, non-ideal signals encountered in real-world instruments. Thus phase algorithms can be optimized and adapted to the particular application at hand. After a review of the basic Fourier description of phase algorithms, several cases are discussed demonstrating this ability. These cases include phase shift error, non-sinusoidal. !26
