Question

What is leakage in the content of energy density spectrum estimate?

Answer 1

Therefore, when performing Fourier or spectral analysis on finite-length data, you can use windows to minimize the transition edges of your sampled waveform. A smoothing window applied to the data before it is transformed into the frequency domain minimizes spectral leakage. Effect of the Hanning Window on a waveform.

Answer 2
