A fourth order, Type I, linear phase, FIR filter, h[n], is to be designed using the window method. The ideal impulse response of the filter is defined as: hd[n] = sin([pi/4][n - N/2]) / ([n - N/2]pi) , where N is the filter order and 'pi' denotes the mathematical (irrational) constant number 3.14159 Given that a stopband attenuation of 50 dB is required, a) Find and sketch h[n] b) Determine the transfer function of the resulting digital filter c) Draw the filter block diagram d) Determine whether this filter is stable, justifying your answer.
