Problem 2: An IIR filter s given in terms of its Z Transform transfer function: Y(z) X(z (1-0.22):-: +0.3z H(z) = : 2.1. Find the filter difference equation representation. What is the order of the filter? Why? 2.2. Use long division to find the first 10 samples of the filter's impulse response h[n]. Then verify your result using the MATLAB "impz" command. 2.3. Find the poles and zeros of H(z) and estimate the magnitude frequency response H(e)| explaining your answer. Use MATLAB "freqz" command to plot the filter's discrete-time frequency response, between the normalized radian frequencies of-m and . Compare the two plots. 2.4. Show the block diagram of the filter's structure, using z blocks, signal adder blocks and multiplication by a constant blocks.
