in 1. Compute the 8-point FFT of the length-8 signal x = [5,-1,-3,-1,5,-1, -3, -1] Note that these samples are the first 8 samples of x(n) = 4 cos + cos (in) [10 Marks) 2. Discuss whether the 8 computed FFT values accurately represent the expected spectrum of x(n). What FFT indices correspond to the two frequencies of the cosinusoids? [10 Marks)
