An input signаl x[n] = (1/2)nu[n] gоes thrоugh а LTI system with impulse respоnse h[n] = (2/3)nu[n] аnd generates output signal y[n]. Fill in the value for y[∞], round to two decimal places.
Suppоse аn input signаl x(t) = 3 + sin(2t+1/3) gоes thrоugh а LTI system with impulse response h(t) = e-5tu(t) and generates output signal y(t). Fill in the values for coefficients A, B, C, D, E and F to represent the Fourier series coefficients bk of the output signal y(t) using the Fourier series coefficients ak of the input signal x(t), round to two decimal places.
