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 WebBesides, this work proposes a circular shift scheme that simulates the random signal cropping in the inference phase and thus ensures the shift-invariant property of adversarial perturbations. In addition, this work designs a composite loss function that improves the imperceptibility of the adversarial perturbation in both time and frequency ... tso readyモード
