Sheet Name

The name of the worksheet in Excel where to copy the numerical results.

TopLeft

Specifies the Excel cell where the results are copied. Should be in the form
CR where C is Excel column name, R is the row number. For example, A1
is the top-left cell in the worksheet.

Algorithm


The power spectrum is calculated for the specified number ( Number of Shifts ) of windows. For
each window:


Normalization


If Normalization is Raw PSD, the power spectrum is normalized so that the sum of all the spectrum
values equals to the mean squared value of the Signal.


If Normalization is Log of PSD, the power spectrum is calculated using the formula:

power_spectrum[i] = 10.*log10(raw_spectrum[i])
