Question

For a filter with the impulse response h(n) = 1/3, 0 lessthanorequalto n lessthanorequalto 2 its difference equation is a. y(n) = 1/3 x(n) + 1/3 x(n - 1) + 1/3 x(n - 2) b. y(n) = 1/3 x(n) + x(n - 1) + x(n - 2) d. y(n) = 1/3 e^x(n) The filter y(n) = 0.8x(n) - 1.3y(n - 1) is stable. True False An IIR filter with impulse response h (n) = 0.3 times 0.9^n u(n) has the frequency response: a. H(e^j ohm) = e^-j ohm/1 - 0.9e^-j ohm b. H(e^j ohm) = 0.9/1 + 0.3e^-j ohm c. H(e^j ohm) = 0.3/1 - 0.9e^-j ohm d. H(e^j ohm) = 0.3/1 + 0.9e^-j ohm
