Problem 6-1 Consider the signal x(t): x(t)=1+2 cos(2π(5)t +π/4)+5 cos(2π (35)t π/3). Sketch the spectrum of this signal. Problem 6-2 Consider the signal y(t) given below: == y(t) = cos (2π(75)t + $ (2π (75) + 31/3) + πT + cos (2π(75)t (2π (7 Π 1 + cos (2π (75) - 17/7). Simplify y(t) and express it as a single sinusoid: y(t) = A cos(2 fot+) where the values of A, fo, and o are specified.
