PROBLEM 4.3.* Suppose that a continuous-time sinusoid ä(t) is sampled at a sampling rate of 6000 samples/sec, resulting in the following discrete-time signal: x[n] = 6cos(лn/3 + 0.1). Knowing x[n] does not uniquely determine x(t); there are many continuous-time sinisuoidal signals x( t) that when sampled would produce this x[n]. Name three that have a frequency less than 8 kHz. In other words, specify three different continuous-time sinsusoidal signals x₁(t) A₁cos (2πf₁t+ 9₁), x₂(t) = A₂cos (2f₂t +9₂), and x3(t) = Acos(2nft +93) that could have produced this particular x[n], subject to the constraint that 0 < f; < 8 kHz in all cases. = PROBLEM 4.3.* Suppose that a continuous-time sinusoid ä(t) is sampled at a sampling rate of 6000 samples/sec, resulting in the following discrete-time signal: x[n] = 6cos(лn/3 + 0.1).
