Hello All, I believe a lot of the people on this ng are users of Matlab and heavily into mathematics, so here is my question. I am trying to integrate a cosine function. If I compare the analitical formula result with the numerical integration result using cumsum(), there is a small difference. Is there anything I can do to minimize that difference, ideally make it zero? Unfortunately...

I did not know where to ask this, I thought some experts here might know. I am writing a basic digital signal processing package in Mathematica (for me, for school work, and demos that I write, nothing commercial, will all be free code) which I use to do my housework, etc... I am actually trying to implement from scratch in Mathematica many of the Matlab useful DSP design functions whe...

Hello all...I'm new to the group and relatively new to Scilab. I'm trying to convert a section of code from Matlab to Scilab (please don't ask "why?" as I'm still trying to figure that one out myself...suffice it to say it is "because I have to"), and I'm completely stuck on converting the following Matlab code: % y is a (1500,1) matrix of numbers (floats) x = remez(16,[0 .5],[0 pi/2],'d'); x...

For the question below i was looking for help since some parts of it i don't get. For part A I import the data in matlab and then plot it using the plot function. i get my x-axis as the number of samples which is 16384 and then the y is the values of the signal. but i dono if i am drawing it correct. should it be in any diff format in terms of x-axis. maybe freq? For part B i found t...

Hi, When I try to design an equiripple FIR with matlab, the script and parameters at the end of this message results in a satisfying filter. (0 dB at DC) However, when I decrease Fpass to 120, the passband has a (flat) DC attenuation +/- 33dB. It seems that the passband suffers increasing attenuation when Fpass is decreased below some threshold. Has anyone an explanation for this? ...

Hey all, this is a bit off topic but I thought I'd post here as somebody may know what the problem is. I've ported my web stuff to a new host and now the links to the matlab code no longer work. Specifically, if you go to the bottom of: http://www.ericjacobsen.org/fe2/fe2.htm and try to get any of the matlab source files it claims the page doesn't exist (at least, that's what it does...

Greetings, I am a student from Vienna, Austria and working on my bachelor of arts research project. I am testing the effect of shelf filtering in an specialized surround sound system on the sonic image. ok, you don't have to know what that means :) But i have a problem. I need the FIR filters (because i got a lot of hints that they would work a lot better) in MATLAB format but i never l...

So I'm trying to implement the inversionless Berlekamp-Massey algorithm in Matlab, and I'm having a devil of a time. I've gotten it to the point that it'll calculate correct polynomials for a simple (7,3) code (from a chapter by Bernard Sklar on the subject) but it falls apart when I give it a larger (204,188) code (from ITU-T J.83), and I have no idea why. Could it have something to do with ...
