Due ?, 200? ELE 324 - TELECOM I HW 1 We study Amplitude Modulation in this homework. i) Generate a carrier wave c(n) with (normalized) frequency fc=0.25 : c(n) = cos(2 π fc n) for n=1,2,…,256. Plot c(n) and its magnitude spectrum (use abs and dft commands). ii) Generate a modulating tone signal with frequency
