NyquistShannonAbtasttheorie
The Nyquist-Shannon sampling theorem is a fundamental principle in digital signal processing. It states that if a function contains no frequencies higher than f, then it can be uniquely determined from samples taken at a rate greater than 2f. This rate, 2f, is known as the Nyquist rate.
Essentially, the theorem provides a mathematical guarantee that a continuous analog signal can be perfectly reconstructed
The theorem has widespread applications in fields such as telecommunications, audio and video recording, and image
