Reconstruction of cubic and quadratic phase components of a multicomponent input signal: (a) Reassigned spectrogram of the output signal of the proposed TCR filter. Gaussian window width is 9 samples. (b) Real part of the desired signal in Equation (40). (c) Real part of the normalized output signal of the proposed TCR filter. (d) AF-WD of the filter output signal when the TCR mask is selected to isolate the horizontal line in Figure 2c. (e) Real part of the quadratic phase component in Equation (39). (f) Real part of the normalized output signal when the TCR mask selects the quadratic phase component.
