I have to repeat it many times because I keep getting the answers that I don't want. I posted this question here before (3 times), the answer was not right I am posting again and all I am asking is PLEASE dont copy and past the solution from the answer that was given here earlier , because it is wrong! I just need an explanation on how to solve this question, it is supposed to be fast and not long solution. I will really appreciate the help. Thank you

Question 3 [15pts] Let us consider the following signals: x(t) = cos(211 2 t) + cos(21.3.t) - cos(211 18 t) and y(t) = hp(t) * x(t) where hup(t) is the impulse response of an ideal low-pass filter with frequency response H(f) = 11 (2) We are going to sample these signals taking 16 samples at a sampling frequency Fs, and then look at the values of the DFT. For example, if Fs = 32, the figure below represents the amplitude of samples of the DFT of x[n], XK. |Xxl 18 16 14 12 10 8 6 4 2 0 0 1 2 3 4 5 6 7 9 10 11 12 13 14 15 8 k. Sketch the following a.
