发帖数: 176 | 1 Forgot who asked about an "easier" understanding about Fourier analysis.
Today i was reading a paper on wavelet time series analysis, the author
summerized Fourier analysis as follows:
Traditional Fourier analysis partitions the total power (variance) of the
time series between sinusoidal components at different frequencies.
I think it's neat. | k******g
