Q. An analog signal x(1) = 2 cos(800at) is to be ideally sampled with a sampling
frequency higher than the Nyquist rate by 50%.
1. Sketch the spectrum of the message signal X(f).
2. Calculate the sampling frequency.
3. Sketch the spectrum of the sampled signal X,().
4. Determine a possible range for the cutoff frequency of the low pass filter
required to recover the original message signal.
