The Sub-Band decomposition of Fluctuated signals for the Estimation of Power Spectra
The noise spectroscopy is used to determinate quality and reliability of semiconductor materials. We have used the means of time-frequency analysis for processing of long time duration stochastic signal. Tree-structured FIR filter bank implemented in a recursive way for octave dividing frequency band was designed as full parallel computational algorithm for power spectral density estimation. In the very low frequency area we will obtain high resolution and low level variance of PSD.
