The magnitude and phase are given by |X2(Ω)|=11+Ω2,∠(X2(Ω))=−tan−1Ω. Computing for different values of Ω we have Ω|X2(Ω)|∠(X2(Ω))010112=0.707−π/4∞0−π/2, i.e., the magnitude spectrum decays as Ω increases. The following script gives the neces...
An example of a particular sinusoid graphed in Fig.4.6 is given by where That is, this sinusoid has amplitude 1, frequency 100 Hz, and phase zero (or , if is defined as the zero-phase case). Figure 4.6 can be viewed as a graph of the magnitude spectrum of , or its spectral ...

python implementation of Welch's method for estimating the power spectra, complex cross-spectrum, magnitude-squared coherence, and phase spectrum of unevenly spaced, bivariate time series - sdrastro/NWelch
In this paper, a new method is introduced for designing signals that have low cross-correlation among them with constant passband magnitude spectrum and quadratic phase. It is shown that in order to get low values of the cross-correlation magnitude between any two signals in the set, the coeff...
