Signal sampling theory
WebMar 4, 2024 · Basics of the sampling theory are outlined to show that the lower bound of signal sampling rate sufficient for signal reconstruction with a given accuracy is equal to the spectrum sparsity of the ... WebFirst, classical sampling theory deals with the question of sampling infinite length, continuous-time signals. Compressed sensing, in contrast, is a mathematical theory that disregards the physical-continuous time aspects of the signal, focusing instead on measuring or projecting finite dimensional vectors in R N to lower dimensional ones in R M .
