WebThe shift theorem says that a delay in the time domain corresponds to a linear phase term in the frequency domain. More specifically, a delay of samples in the time waveform corresponds to the linear phase term multiplying the spectrum, where . 7.13 Note that spectral magnitude is unaffected by a linear phase term. That is, . Linear Phase Terms
