WebThe sampling theorem, introduced in Section 7.1.3 , makes a precise statement about the conditions on , the number of samples taken, and the reconstruction technique used under which is exactly the same as . The fact that the original function can sometimes be reconstructed exactly from point samples alone is remarkable. WebMay 6, 2024 · The Nyquist sampling theorem, or more accurately the Nyquist-Shannon theorem, is a fundamental theoretical principle that governs the design of mixed-signal electronic systems. Modern technology as we know it would not exist without analog-to-digital conversion and digital-to-analog conversion.

WebThe Nyquist sampling theory dictates that a signal that is sampled with a dwell time DW can only accurately represent signals up to a maximum frequency ± f N, where f N = 1/(2 × DW). In the absence of filtering, frequencies outside this Nyquist threshold will fold back into the spectrum such that a signal of frequency f N + δ f will be represented in the spectrum at … 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 ...
