Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean squares of the error signal (difference between the desired and the actual signal).
The weights update Formula for every Iteration is Wt new=Wt old + mu * error *input;
inp=inp-(min(inp)); % required for audio signals
h=[1 -4 6 -5 2]; % Known System papametes for a low Pass filter h
