I tried to run the following commands in the example of the PMTM documentation: randn('state',0); fs = 1000; t = 0:1/fs:0.3; x = cos(2*pi*t*200) + 0.1*randn(size(t)); [Pxx,Px…
I am using SPTOOL to graphically view my signal. I would like to use the vertical markers to crop and save portions of my signal. …
I have a filter design GUI where a user can input the poles and zeros of the desired response. I am using the FREQZ command to plot the frequency response of the filter in the GUI.…
How do I control the individual products and accumulators of my DFILT object in Signal Processing Blockset 6.9 (R2009a)? I can set the properties for my DFILT object, but I do n…
Why does the cascade of a lowpass and a highpass Butterworth filter not produce the same results as a bandpass Butterworth filter in Signal Processing Toolbox 6.10 (R2008b) ? I cre…
Is it possible to add an option to the SPECTROGRAM function to return/ display the DC frequency in the center of the axis in the Signal Processing Toolbox 6.11 (R2009a)? When I exe…
Why do I receive a segmentation violation when I pass in an INT16/INT32 datatype into the RESAMPLE function in the Signal Processing Toolbox? When I type z = int32(50*rand(…
What is an efficient way to calculate the FFT of a signal at specific frequency points in Signal Processing Toolbox 6.12 (R2009b) ? Normally, the FFT function returns the frequency…
What is the mathematical relation between the output parameters S and P in the function definition of spectrogram in Signal Processing Toolbox 6.9 (R2008a)? I would like to know th…
I was using CSD from the Signal Processing Toolbox to compute power spectral densities but since Release R14 I am receiving a warning that CSD has been replaced by CPSD and CSD sti…
