Hi I have been trying to modify one of the exercise codes given in Dr Rulp
Chassaings Book 'Digital
Signal Processing with the C6713 and C6416 DSK," Wiley, 2005.
Ive attached the modified main file 'AdaptIDFIR1.c' as well as the
original
project.The only difference being tht ive used external input (line or mic)
instead of random noise used in the original. and NLms algo is used instead
of LMS
However the output is always a loud noise.
Ive tried a very basic code
x=input_sample();
inp[0]=x;
for(i=0;i
{
y+=inp[i]*w[i];
inp[i+1]=inp[i];
}.
.
.
.
**output_sample(x);
Even though i am not modifyin x the output gets noisy and at times the
output is indistinguishable
Any kind of advice would be really appreciated
Unable to perform adaptive filtering in C6713
