The segregation of Fourier spectrum of multi-component signal is performed using the detection of peaks and then the evaluation of boundary points. For non-stationary signals, the Fourier Bessel Series Expansion (FBSE) is the natural choice as it uses Bessel function as basis for analysis and synthesis of the signal. The FBSE spectrum has produced the number of frequency bins same as the length of the signal in the frequency range [0, ].
The segregation of Fourier spectrum in a multi-component signal is achieved by detecting peaks followed by evaluating boundary points. For non-stationary signals, the Fourier Bessel Series Expansion (FBSE) serves as an appropriate method since it employs Bessel functions as the basis for analyzing and synthesizing the signal. The FBSE spectrum generates the same number of frequency bins as the length of the signal within the range [0, ].
