Question 84: [Basic] For a LTI system with the impulse response h(t) (a) Find the frequency response H(jw). = sin(2t) πι This LTI system is an ideal low-pass filter. What is the cutoff frequency. (c) If the input x(t) = cos(t) + sin(3t), find the output y(t) = h(t) * x(t). Question 85: ([Advanced] p. 337, Problem 4.18) Find the impulse response of a system with the frequency response H(jw) = (sin² (3w)) cos w w2
