SIGNALS and SYSTEMS HOMEWORK-IV 1. Let X(t) be the input to an LTI system with unit impulse response h(t), where x(t) = e-tu(t) h(t) = u(t -3). Determine and plot the output y(t) = x(t) *h(t). Both analytically and graphical method. (25 p)
Suppose that for the LTI system depicted in the following figure (a), the impulse response and the transfer function are given by h(t) = e-tu(t) H(S) = s+1 1 H 100 The input signal x(t) is the square wave of Figure (b), where t is in seconds. Since the fundamental period is To = 2π, the fundamental frequency is ao-2π/L = 1 rad/s and kaa-k. 3t (a) Use the Table provided to find the exponential Fourier series of the signal...
A cascaded system that consists of an LTI system and a delay system is shown in Figure Q4(b). The input signal X(t) and impulse response of the LTI system, h(t) are given as the following: x(t) = 6-2&u(t) h(t) = e-fu(t) Determine: The Fourier transform of y(t).
