5.37 Non-causal filter-Consider a filter with frequency response HG2)sin2) or a sinc function in frequency. (a) Find the impulse response h(t) of this filter. Plot it and indicate whether this filter is a causal system or not. (b) Suppose you wish to obtain a band-pass filter G(jS2) from Hj2). If the desired center frequency of |G(jS2)| is 5, and its desired magni- tude is 1 at the center frequency, how would you process h(t) to get the desired filter? Explain your procedure. (c) Use symbolic ΜΑΠΑΒ to find h(t), g(t) and GUS2) Plot lH(jQ)I h(t), g(t), and|G(j2)l Compute the Fourier transform using the integration function.
