5. An analog signal's one-sided spectrum is shown below. The sampling rate is chosen at a) 60 kHz and b) 40 kHz. Draw the spectrum of the sampled signal in each case from 0 to 180 kHz. Does aliasing occur? Explain. 1.5 0.5 0 510 15 20 25 30 35 40 45 50 Frequency (kHz) 5. An analog signal's one-sided spectrum is shown below. The sampling rate is chosen at a) 60 kHz and b) 40 kHz.
