non-uniform spectral interpolation in the frequency domain 3 23 (1/14/2009 11:58:30 PM) comp.dsp Hi, I'm researching ways to interpolate the sampled spectrum of a signal as given by a 512 point FFT. I typically only use the output of the FFT as is, but I occasionally need to resample the continuous spect... Gilead

c language mex file problem 4 15 (11/6/2007 2:16:31 AM) comp.soft-sys.matlab I'm new to Matlab mex functions and my experience in C itself is pretty limited, so maybe someone can help me out here. I want the code below to basically perform a typecast from uint16 to double. (This is not... Gilead

algorithm for computing partial DFT 2 18 (5/18/2007 7:55:33 AM) comp.dsp I have an extra-credit homework problem that I'm working on, and I'm hoping someone can get me pointed in the right direction. The set-up is that I have an N-sample complex data set, where N is large and even,... Gilead

longer FFT v. shorter FFT with interpolation 2 30 (5/9/2007 11:44:31 PM) comp.dsp I need to analyze the magnitude spectra of some data sets. Every data vector will have 128 or fewer complex samples. I window all the data using a Chebyshev window with a certain level of relative sidelobe at... Gilead
