Consider the following continuous-time signal: x(t)-9 sin (9mt) + 14 cos (12mt) x(t) is sampled at a rate 4 times the Nyquist rate, to produce a discrete-time signal xin). Calculate the power of the sampled waveform. (Hint: use the simplest way possible, even if that means calculating the power of the continuous time signal in one step) Type your answer...
