Problem 3.1 (10 points). Consiuuan analog signal x(t) consisting of three sinusoids of frequencies of 1, 4, and 6 kHz: x(t) = cos(24t) + cos(8nt) + cos(127t) where t is in milliseconds. Show that if this signal is sampled at a rate of f = 5 kHz, it will be aliased with the following signal, in the sense that their sample values will be the same (5 points): Xa(t) = 3 cos(2nt). On the same graph, plot (2.5 points) the two signals x(t) and xa(t) versus t in the range 0
