Question: A continuous-time LTI system is represented by the ordinary differential equation where x(t) is the input and y(t) the output. (a) Determine the frequency response

A continuous-time LTI system is represented by the ordinary differential equation

dy(t) dt = -y(t) + x(t) %|

where x(t) is the input and y(t) the output.

(a) Determine the frequency response H(jΩ) of this system by considering the steady-state output of the system to inputs of the form x(t)=ejΩt, for ˆ’ˆž < Ω < ˆž.

(b) Carefully sketch the magnitude, |H(jΩ)|, and the phase, ˆ H(jΩ), frequency responses of the system. Indicate the magnitude and phase at frequencies of 0, ±1, and ±ˆž rad/sec.

(c) If the input to this LTI is x(t) = sin(t)/(Ï€t), determine and carefully plot the magnitude response |Y(Ω)|of the output, indicating the values at frequencies 0, ±1, and ±ˆž rad/sec.

dy(t) dt = -y(t) + x(t) %|
