correlation formula help?
So I'm reading this paper, and they're deriving a formula for the correlation between a received signal (r(n) a superposition of multipath copies) and a known copy s(n). The formula can be seen here: I get they're substituting the definition of r(n) back into the s... 25 May 2010 00:30
magnitude response of IdQ-QdI
I am trying to find the mathmatical magnitude response of the following FM demodulation equation: I[n-1]*(Q[n]-Q[n-2])-Q[n-1]*(I[n]-I[n-2]) ----------------------------------------- I[n-1]^2+Q[n-1]^2 How do I represent I and Q in terms of some x[n] to find the z transform of the equation? I know I[... 25 May 2010 16:50
Helium Voice effect algorithm
Hi, hopefully I'm writing to the correct group. I'm looking for a project to start learning DSP programming, and an idea that come to my mind was to implement an algorithm that, getting my voice as input, would output the voice with the helium effect. I've googled a bit to see if there is already an algorit... 25 May 2010 10:11

DSP/BIOS Stack Questions
a. The javascript bios.MEM object (in the .tcf file) has a "global stack" that can be manipulated with bios.MEM.STACKSIZE and bios.MEM.STACKSEG. What is the "global stack" used for? b. Where does the C compiler stack get initialized prior to main()? c. Tasks (and probably other threads) have their own... 22 May 2010 10:30
Notch comb filter coefficients
Hi all. I've found in MATLAB help that a notching comb filter has following tranfser function: H(z) = b*(1+z^(-N))/(1+a*z^(-N)) where N is the number of notches. How to determine coefficients a and b with respect to real-world parameters such as sampling frequency, notch frequency and notch bandwidth/resp. atten... 24 May 2010 16:48
DSP/BIOS Dynamic TSK_create()-ion under TMS320C6418
I'm trying to get three dynamically-created (versus creating statically under the Tconf gui) tasks running but the tasks just won't run. They are successfully created (TSK_create() returns non-null) but never run according to the event log. This is taken from the tsk example under the bios directory. Any ideas/... 21 May 2010 10:34
