Let s(t) = cos(20īt) is sampled at fs = 16Hz. The resulting sampled signal, x(t), is passed through an ideal low pass filter with a cut off frequency of f;/2 and magnitude of 1/fs, and the output of the system is y(t). a. Plot x(t) in time AND frequency domain. Carefully insert x-axis, y-axis, and key values. b. Find the recovered signal, y(t). Compare y(t) with s(t). Provide explanations if you find y(t) #s(t).
