Sampling and reconstruction are two essential operations in signal processing. Sampling is the process of converting a continuous-time signal into a discrete-time signal by extracting samples, which are values of the signal at points in time. Reconstruction is the reverse process of constructing an analog signal from a discrete-time sequence. Sampling and reconstruction have applications in areas like digital audio, analog to digital conversion, speech and pattern recognition, modulation and demodulation, sensor data evaluation, radar, radio navigation, biometric identification, and surveillance systems.

2. Sampling and reconstruction are two of the most essential and widely used
operations in signal-processing systems.
 Sampling is a process of converting a continuous-time signal into a discrete-
time signal.
 Reconstruction is the process of construct an analog signal from a discrete-
time sequence

4. • Sampling: 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". A sample is a value of the signal at
a point in time .
• A sampler is a subsystem or operation that extracts samples from a continuous signal. A theoretical ideal
sampler produces samples equivalent to the instantaneous value of the continuous signal at the desired
points.
