Design a causal, FIR bandpass filter with cutoff frequencies at w1 = 0.3pi and w2 = 0.6pi. Use a Hamming window. Let the filter length be 7 or 8. Design four different filters: Type I, Type II, Type III, and Type IV. Derive the equations for the ideal impulse response for these filters. Then multiply the ideal impulse response by the appropriate window function. Print the h(n) values for each filter. Plot the magnitude frequency response of each filter on the same semilogy plot (using MATLAB). Discuss the results. You may want to use the hamming and sinc functions.
