thanks for thr help rahul

FinallyI decidedto implement adaptive filter with FIR (LMS) ,I builtmy codebased on a adaptive filter lms code from c64xx Library.

i attached my code...

I puta music signl at the entranceXand add to Xsinesignal(noise-frequency1Khz), D isthe desired signal(the musicwithout thenoise),E-is the error, Y is the out put.

WhatI expectedto getis a 1Khz on E(after a time) and the music on Y.

but im having a problem...what i get is a random nois(not what i added) on Y and a music with a noise(1Khz) on E...
