Report Assignment
Design two low pass filters, FIR and IIR filters, that have the same cutoff frequency
of 𝜔.
Assignment 1: Compare outputs of the two filters when the input signal is a
rectangular wave. Describe the differences and explain why such differences appear.
Assignment 2: Prepare an input signal that consists continuous sinusoidal signals of two frequencies, 𝜔 and 3𝜔 . The two frequencies should satisfy 𝜔 𝜔 3𝜔 . Compare outputs of the two filters and describe the meaning of “linear phase”, based on the difference in the output waveforms.
Filters and input signals should be designed so that the results exemplify the objectives of the assignments. The report should provide design parameters sufficient for reproduction of the results.
