sci transmit problem
hi, good day to all. i tried to send code serially by assigning a value to the SCITXBUF_A (im using tms320f2812). From what i understand, when the buffer is full...data is automatically sent serially. The problem is, i viewed the registers and found that even if the buffer is full, nothing is send over the trans... 27 Jun 2008 10:05

Optimization of mutual information between two images
Can anyone help me with optimization problem of minimization of mutual information between two images; one test and other reference image, subject to some equality constraints?The goal is to find the optimal transformation parameters(for registration).Thanks for any related stuff and your suggestions Sofi ... 30 Jun 2008 05:32

Calculating cross-correlation from two auto-correlations
Hello, I have two autocorrelation sequences of unknown signals A and B, and I need to calculate cross-correlation between these two. Is there any way to do that without performing spectral factorization? Thanks in advance. Tony ... 28 Jun 2008 02:29

fft length
on what basis the fft length is calculated related to the sampling frequency?I want to search for a maximum peak by obtaining the spectrum of the signal.I am working on demodulator in that my task is to acquire the carrier from the receive modulated signal.Modulation used is BPSK.It can be used for 300,600,1200,2... 27 Jun 2008 08:02

5 Stages CIC Filter Matlab Simulation Problem
I implemented the matlab simulation model according to hardware architecture.The impulse response is ok when the impulse length is short.But when I increase the length of impulse stimulus, I found increasing spurs. I don't know whether this is caused by the instability of the filter or some other reasons. Attached ... 27 Jun 2008 04:58

IIR notch filter
I am trying to design a second order digital IIR band stop (notch) filter with the following specs: 3dB cut off frequencies: 55Hz and 65Hz I want the notch at 60Hz with atleast 90dB attenuation at the 60Hz. Sampling frequency: 200hz I tried various filter configurations like a Butterworth or Chebyshev but cou... 27 Jun 2008 14:12
