Circular time shift property

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 Web2.16.2 Time Shift. Linear, shift invariant, discrete time system are invariant regarding shifts in their independent variables. This property permits the initial value of the independent variable to be arbitrarily set to zero () during the analysis of such systems. This can often simplify the analysis.

WebJul 15, 2015 · You must zero-pad, whether implementing the delay in the time domain or the frequency domain. (Consider this: by delaying, you are making the signal longer .) Implementing the delay with the FFT implements a circular shift. If you don't pad and you use the FFT, the data will simply wrap around on itself.
