Time-scaling of signals
WebMay 22, 2024 · Time Scaling. This property deals with the effect on the frequency-domain representation of a signal if the time variable is altered. The most important concept to understand for the time scaling property is that signals that are narrow in time will be broad in frequency and vice versa.

WebAug 11, 2024 · However, the scaling is quasi-static coefficient-only processing and cannot be applied to the real-time input signals directly. Based on the noise analysis in Section 3.1 , a new adaptive scaling algorithm is proposed in this section, where both the input signal and the filter coefficients are adaptively scaled to the high accuracy region of stochastic … WebAs a time-domain approach, it works best for small speed changes and quasi-periodic, monophonic signals. Some of our enhancements are especially effective for small, others for large speed changes. As a consequence, significant improvements for all scaling factors are achieved extending the usability of the new scheme to larger speed changes and more …
