EEL5701: MATLAB#2

Due Tuesday, June 3 at the beginning of class, late assignments will not be accepted. Please turn in all of the Matlab code that you write.

1. Consider a 60 Hz continuous-time signal given by

   

   Plot using a very small . Show only a few periods in your plot.

2. Sample the continuous signal using a sampling period of T=7ms. Plot these samples on the same plot given in part 1.
3. Reconstruct the original signal using these samples using the sinc interpolation formula. Show the reconstructed curve on the same graph given in part 1. What is the maximum error at any point in the reconstruction?
4. Repeat part 3 above using the spline interpolation formula. Comment on the difference between the spline and sinc interpolations methods.
