Q54
An LTI system having transfer function s^2 + 1s^2 + 2s + 1 and input x(t) = sin(t + 1) is in steady state. The output is sampled at a rate ωs rad/s to obtain the final output y(k). Which of the following is true?
An LTI system having transfer function and input x(t) = sin(t + 1) is in steady state. The output is sampled at a rate ωs rad/s to obtain the final output {y(k)}. Which of the following is true?
