Question

The reconstruction of the signal from its samples as a linear filtering process in which a discrete-time sequence of short pulses (ideally impulses) with amplitudes equal to the signal samples, excites an analog filter.

(a) True

(b) False

The question was posed to me during an online interview.

My doubt stems from Digital to Analog Conversion Sample and Hold topic in portion Sampling and Reconstruction of Signals of Digital Signal Processing

Answer 1

Correct option is (a) True

The explanation is: The reconstruction of the signal from its samples as a linear filtering process in which a discrete-time sequence of short pulses (ideally impulses) with amplitudes equal to the signal samples, excites an analog filter.
