Sampling - Signals & Systems Questions and Answers - Sanfoundry

WebThe answer is given by the Nyquist-Shannon sampling theorem, that may be simply stated as follows: The minimum sampling frequency of a signal that it will not distort its underlying information, should be double the frequency of its highest frequency component. If fS is the sampling frequency, then the critical frequency (or Nyquist limit) fN ... WebEquation 13, commonly called the sampling theorem, is the result for which we have been working. It shows that sampling in the time domain at intervals of T seconds replicates the spectrum of our unsampled signal every 1/T cycles per second. ... Figure 3 depicts a sampled signal suffering from aliasing. WebMay 4, 2024 · Sampling Theorem states that a "band-limited" signal can be exactly reproduced if it is sampled at a frequency F, where F is greater than twice the maximum frequency in the signal. But mathematically, a signal can never be truly band-limited. A law of Fourier transformations says that if a signal is finite in time, its spectrum extends to ... chloe ramseyer

WebSignal Sampling and Reconstruction. A continous-time signal x (t) is sampled at a frequency of w s rad/sec. to produce a sampled signal x s (t) . We model x s (t) as an impulse train with the area of the n th impulse given by x (nT s ). An ideal low-pass filter with cutoff frequency w c rad/sec. is used to obtain the reconstructed signal x r (t).
