Power Spectra for Analytic and Numerical Data
Power Spectra for Analytic and Numerical Data
Consider a function defined by , in which you can vary the parameters , , , and . This Demonstration calculates the power spectrum of based on the method described in [1]. In addition, the power spectrum of raw data is obtained. Power spectra represent a generalization of Fourier analysis, applicable even when the Fourier transform is not well defined.
