The XCOV function in the Signal Processing Toolbox 6.8 (R2007b) has four distinct options: 'biased', 'unbiased', 'coeff', and 'none'. I would like to be able to create unbiased est…
Can I specify the detrending option in the PWELCH function in Signal Processing Toolbox 6.0 (R13) similar to the syntax of the PSD function? I can detrend my signal using the PSD f…
Why do I get a high frequency oscillation when I take the FFT of a rectangular pulse? I am taking the FFT of a Rectangular Pulse and I expect a nice smooth Sinc wave. But what I…
What is the 'periodic' sampling option in the HAMMING function used for in Signal Processing Toolbox 6.2 (R14)? The HAMMING window function has a secondary argument named 'sflag…
I would like to know if I need to multiply the result of PWELCH by "norm(w)^2/sum(w)^2", where w is the window vector? Also, I would like to know if the old function PSD can be …
Why am I unable to start FDATool in the Signal Processing Toolbox 6.1 (R13+) when the DSP Blockset and/or Filter Design Toolbox license has expired? I receive the following errors …
Why does the FILTFILT documentation not mention the effects of truncation, while providing a short input sequence to an IIR filter ? I am using the FILTFILT function to plot th…
Why does the documentation for the XCOV function in the Signal Processing Toolbox 6.8 (R2007b) refer to Gaussian random variables as "Uniform noise with mean = 0.5"? The docume…
Why does the FIRPM function yield different output in MATLAB 7.2 (R2006a) and MATLAB 7.3 (R2006b)? The following code produced different figures in MATLAB 7.2 (R2006a) and MATLAB…
How can I make the FREQZ function (in the Signal Processing or Filter Design Toolboxes) produce a plot with a logarithmic frequency axis? The FREQZ function plots frequency on a li…
