Design a cascade system combining two filters. Given the impulse responses h1(t) = e^(-t)u(t) and h2(t) = sin(t)u(t), find the overall impulse response h_eq(t).
💡 Hint: Set up the convolution integral properly, and pay close attention to the limits of integration.
You are given a feedback system where the output is fed back with a gain of 0.5. How does this feedback affect the steady-state response of the system?
💡 Hint: Create a transfer function for the closed loop and check the poles for real parts.
