Lab 4: Sampling, Nyquist, Eye Diagrams, PR Signaling 1 Introduction Pulse amplitude modulation (PAM) and the sampling theorem are closely related. For the sampling theorem the goal is to convert a bandlimited CT signal x(t) to a DT sequence xnby sampling …

If, however, fs<2W, then aliasing occurs, and recovery of the original analog signal will not be possible. The Nyquist-Shannon Sampling theorem is a fundamental one providing the condition on the sampling frequency of a band-width limited continuous-time signal in order to be able to reconstruct it perfectly from its discrete-time (sampled) version. These results lead to the well known sampling theorem, also called the Nyquist-Shannon theorem: A signal can be completely reconstructed (without information lost) from its samples taken at a sampling frequency if it contains no frequencies higher than , called the Nyquist frequency. 1.1 The Nyquist-Shannon sampling theorem. The Nyquist theorem describes how to sample a signal or waveform in such a way as to not lose information. This is known as the Nyquist rate. The Sampling Theorem states that a signal can be exactly reproduced if it is sampled at a frequency F, where F is greater than The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signals.

Modern technology as we know it would not exist without analog to digital conversion and digital to analog conversion.

Nyquist limit: the highest frequency component that can be accurately represented: Nyquist frequency: sampling rate required to What is the Nyquist Sampling Theorem? • Formal Definition: o If the frequency spectra of a function x(t) contains no frequencies higher than B hertz, x(t) is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart.
