WebMar 9, 2024 · The study of sampling signals on graphs, with the goal of building an analog of sampling for standard signals in the time and spatial domains, has attracted considerable attention recently. Beyond adding to the growing theory on graph signal processing (GSP), sampling on graphs has various promising applications. In this article, we review current … WebMar 1, 2024 · This leads to a spectral graph signal processing theory (GSPsp) that is the dual of the vertex based GSP. GSPsp enables us to develop a unified graph signal sampling theory with GSP vertex and spectral domain dual versions for each of the four standard sampling steps of subsampling, decimation, upsampling, and interpolation.

Sampling a continuous time signal produces a discrete time signal by selecting the values of the continuous time signal at evenly spaced points in … WebThe sampling process provides the bridge between continuous-time (CT) and discrete-time (DT) signals. Sampling records discrete values of a CT signal at periodic instants of time. Sampling opens up possibility of processing CT signals through finite impulse response (FIR) and infinite impulse response (IIR) filters.

The fact that the original function can sometimes be reconstructed exactly from point samples alone is remarkable.

Functions of space, time, or any other dimension can be sampled, and similarly in two or more dimensions. For functions that vary with time, let S(t) be a continuous function (or "signal") to be sampled, and let sampling be performed by measuring the value of the continuous function every T seconds, which is called the sampling interval or sampling period.
