An example of a particular sinusoid graphed in Fig.4.6is given by where That is, this sinusoid has amplitude 1, frequency 100 Hz, and phase zero (or , if is defined as thezero-phasecase). Figure4.6can be viewed as a graph of themagnitude spectrumof ...
The beginning of the response is difficult to locate in practice, so we use only the magnitude of the time response's DFT Spectrum as input to the neural network, thus eliminating time-shift uncertainty. Especially promising is the Recurrent Correlation Accumulation Adaptive Memory-Generalized ...

yourself too). As in electronics, the term "20 dB" equivalently means "a 10x difference in voltage" AND IT ALSO MEANS "a 100x difference in power".So, in your example, I think it is more correct to simply say that there is a "10 dB difference in the peaks" in the power spectrum...
Sinusoidal parameter estimation methods which operate on the DFT exploit the assumption that the peak in the magnitude spectrum is associated with a complex sinusoid—in this context finding the fractional bin index 𝒦K and peak magnitude 𝒳X of the window transform is considered equivalent to re...
A magnitude-aware training target 𝑇𝑀TM is learned via the STFT (short-time Fourier transform) [5] spectrum of clean speech 𝑠(𝑡)s(t) and mix speech 𝑥(𝑡)x(t). In the speech enhancement stage, the complementary acoustic features 𝐹𝑧Fz extracted from 𝑧(𝑡)z(t), ...
