Question 12

The Inverse Discrete Fourier Transform of the sampled frequency response was taken to obtain the impulse response h(n).

The resulting response was graphed:

XY Plot


The impulse response matches the results obtained in question 5, as expected.

Optional Part

The question was repeated using Matlab and the standard FFT routine using N = 1024.

The graph of the impulse response obtained matches with the manually calculated results:

The frequency resolution was found to be .
