The 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 ...

The theorem states that, if P(D) is a polynomial D-operator, then, for any sufficiently differentiable function y, To prove the result, proceed by induction. Note that only the special case needs to be proved, since the general result then follows by linearity of D-operators. The result is clearly true for n = 1 since WebAug 9, 2024 · The First Shift Theorem tells us that we first need the transform of the sine function.
