1. Using the window method and a nonKaiser window, design a digital highpass filter with Ωs = 0.45π, Ωp = 0.5π, and αs = 60 dB
2. Using the window method with a Blackman window, design a length Lh = 11 digital bandpass filter with Ωp1 = π/4, Ωp2 = 3π/8, and αs = 60 dB. Plot the corresponding magnitude response, and determine the approximate widths of the two transition bands. Lastly, show an efficient block diagram realization of the filter.
