What is sampling and reconstruction of signal?

A continuous time signal can be processed by processing its samples through a discrete time system. For reconstructing the continuous time signal from its discrete time samples without any error, the signal should be sampled at a sufficient rate that is determined by the sampling theorem.

What is meant by reconstruction of signal?

In signal processing, reconstruction usually means the determination of an original continuous signal from a sequence of equally spaced samples. This article takes a generalized abstract mathematical approach to signal sampling and reconstruction.

What is sampling in the signal processing?

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples".

How sampling and reconstruction of discrete-time signal is done?

A discrete-time signal is constructed by sampling a continuous-time signal, and a continuous-time signal is reconstructed by interpolating a discrete-time signal. Figure 11.1: Sampler. Recall that frequency can be given with any of various units. The units of the f in (11.3) and (11.4) are Hertz, or cycles/second.
