Geometric evaluation of the fourier transform

WebGiven the pole-zero plot of a system's rational transfer function H(s), the magnitude and phase angle of the corresponding Fourier transform , i.e., its Bode plot, can be obtained qualitatively by observing the magnitude and angle changes of the zero and pole vectors, as shown below for the first and second order systems. WebFeb 18, 2024 · This type of evaluation methods are usually based on Fourier transform (FT) , wavelet transform (WT) methods, etc. The general framework of spectral domain-based methods is shown in Figure 4 , where H and L represent the high-pass filter and the low-pass filter, respectively, and LL, HL, LH and HH are the corresponding components …
