SpletThe power spectrum (PS) of a time-domain signal is the distribution of power contained within the signal over frequency, based on a finite set of data. The frequency-domain representation of the signal is often easier to analyze than the time-domain representation. Many signal processing applications, such as noise cancellation and system ... SpletNormalization for Spectrum Estimation Spectral leakage can be reduced by using a data window with smaller sidelobes in its transform. For unbiased power spectral density estimates, a data window h[n] should be normalized so that 1 N NX−1 n=0 h2[n] = 1 (7) The Hanning Window The Hanning spectral window is H2(ω) = c2e−jω(N−1)T/2 h 0.5H0 ... klipsch wireless rear surround speakers
