Signal sampling theory
WebThe 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 … WebMar 3, 2015 · The theory follows the same paradigm as classical sampling theory. We show that perfect recovery is possible for graph signals bandlimited under the graph Fourier transform. The sampled signal coefficients form a new graph signal, whose corresponding graph structure preserves the first-order difference of the original graph signal.

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.

WebMay 22, 2024 · Sampling. Sampling a continuous time signal produces a discrete time signal by selecting the values of the continuous time signal at evenly spaced points in time. Thus, sampling a continuous time signal x with sampling period T s gives the discrete time signal x s defined by x s ( n) = x ( n T s). The sampling angular frequency is then given by ...
