Plot FIR system magnitude and phase

x[n]= cos(0.03πn) for N=2000 samples.

for this system which is System Identification

how to do this tasks.

D) Implement the LMS algorithm to estimate the filter coefficients w0,…. w3

μ is assumed to be very small (try μ =0.01).

Plot the learning curves:

1. The error e(n).

2. (J vs iteration steps). Where J is defined to be J=e2(n).

3. (10log10(J) vs iteration steps).

E) Plot the amplitude and phase response for the estimated FIR system at the end of the iterations. Compare it with the given FIR system.
