What is the relation between power spectrum density and auto
Webcorrelation function C, which Krommes also denotes as , can be related to the Fourier coefficients of and , by so the fourth equation above can be written as Setting to consider the auto-correlation function of with itself, we see that the 2-point correlation function is the Fourier transform of the power spectrum, Web0. My aim is to determine the power spectrum of a signal of finite duration using. Its autocorrelation function. Performing FFT directly on the time-domain data. The function is defined as follows in the finite time interval from 0 to 10: cos ( 10 t) + sin ( 20 t) I am using the library FFTW 3.3.4 in C source code and pretty confused about all ...
