can the bessel filter be directly designed in digital domain? Can the bessel filter (of course IIR) be designed directly in digital domain? If so what would be the steps/process. Regards Bharat ... 11 Mar 2010 07:47
Playing polygon games Hi folks. I have an application where I need to process a polygon. The polygon is given as a list of points that tracks the boundary of the polygon. There are two tests that must be done befoe I can do my processing: 1) Ensure that the polygon is simple 2) Ensure that the points track the outline in the count... 11 Mar 2010 04:32

CIC filter Hi all. How do i implement a CIC filter in C? I am using ARM to collect some data with ADC, and now i would like to filter it with CIC filter. I find data about cic, but its mostly theoretical, and i dont really know how to implement it in practice.... ... 11 Mar 2010 07:47

Constructing A[tau*omega] from A[tau, omega] Hello-- I am reading a very interesting paper on acoustics which describes a numerical procedure used to construct a discrete vector of values from a signal. This vector is then used along with some mathematics to calculate the attenuation of a sound pulse through a medium. Essentially, the procedure has th... 9 Mar 2010 16:55

question about fftw3 in fortran, reuse plan, FFTW_MEASURE, FFTW_ESTIMATE, Segmentation fault Hello, I tried to test the sin transform using fftw, met some problems which I had no clue what's the reason. The following is my program, it first does sin transform of sin([1:7]/ 8*pi) use flags :FFTW_RODFT00,FFTW_ESTIMATE and there's no problem.

Whitened Matched Filter I am trying to figure out why all treatments of MLSE receiver for ISI channels use the idea of a matched-filter followed by a noise whitening filter? Isn't the latter a simple inverse of the former? In fact if we simply don't go into the matched-filter/whitening-filter duo, we can still derive what Proakis refers... 9 Mar 2010 14:37
Cancellation of reconstructed digital signal Hello, I have an instrumentation amplifier with a gain of 100. The positive input (AO) is connected to a DAC. The negative input is taken from a previous analog stage and also connected to a ADC --> recorded signal (AI1). I put a replicate of the recorded signal (AI1) at AO. However, I got an amplified signal o... 9 Mar 2010 13:27
How to generate a Gaussian time correlated process? Hi, What is the most efficient way to generate a noise process that is Gaussian correlated in time from a white noise process? I'm having trouble coming up with a simple FIR filter that will do this. Any suggestions? Thanks, ~mohan ... 11 Mar 2010 04:32 |
