Design an FIR low-pass digital filter using window method, with fp=1a kHz and fs=1ab kHz and the sampling frequency is 4ab kHz and the filter exhibits the minimum attenuation of -5a dB in the stop-band where value a and b are to be inserted based on the last digit of your matric number respectively. Compute the digital filter transfer function.
