Question 5 (1 point) Reconstruction of a discrete-time signal using an ideal D-to-C converter to find the original equivalent continuous-time signal requires the summation of scaled and time shifted pulses For reconstruction of a discrete-time signal using an ideal D-to-C converter, check each tru statement and leave unchecked each false statement Perfect reconstruction requires interpolation by summing scaled and shifted ideal sinc pulses which are infinite length and therefore non-causal. Practical reconstruction uses a realizable low pass filter or equivalently, it uses the low pass filter impulse response as the pulse to sum. Sampling slower improves the interpolation for each of the non-ideal interpolation methods Linear interpolation (triangle pulse) provides better reconstruction than zero-order hold interpolation (square pulse) The reconstruction process in a practical system is a cascade of an anti-aliasing filter followed by an analog-to-digital converter (ADC) Save

Explanation / Answer

Correct Answer:

Perfect reconstruction requires interpolation by summing scaled and shifted ideal sinc pulses which are infinite length and therefore non-causal

In the process of reconstruction replacing each sample by a train of sinc pulses,centered at the time of the sample and scaled by the sample value and summing all the functions.
