Problem 1 Fourier transform analysis of previous homework problem. Problem 2 from Homework 3 is revisited. Consider the low-pass system y = -y +2u with input u(t): = -et t<0 t>0

(1) Explain why a Fourier transform approach can be used to solve this problem. Use it to find y(t) and compare the result to the convolution approach from Homework 3.
