1. a) An analog signal contains frequencies up to 12 kHz. (i) What range of sampling frequencies dose allow exact reconstruction of this signal from its samples? (ii) Suppose that we sample this signal with a sampling frequency Fs = 9 kHz. Examine with proper diagram what happens to the frequency component F1 = 6 kHz after passing through the digital to analog converter. (iii) Repeat part (ii) for a frequency component F2 = 11 kHz. b) Why is it necessary to introduce an analog low-pass filter before analog to digital converter? Illustrate the fact with necessary diagram.
