Question: Implement the filter with transfer function given by

     H(z) = 0.4 - 0.8z^-1 + 0.4z^-2

with finite-precision arithmetis given by

    (-1)^s x (0 + 0.significand)

where the significand represents the decimal fraction of the coefficients and is limited to 3 bits with 1 bit allocated for the sign. Compare the magnitude response of the original filter with the magnitude response of the filter implemented with finite-precision representation.
