According to this theorem, the highest reproducible frequency of a digital system will be less than one-half the sampling rate. From the opposite point of view, the sampling rate must be greater than twice the highest frequency we wish to reproduce.* This frequency, half the sampling rate, is often called the Nyquist frequency.

Nyquist-Shannon theorem This claim is possible because it is consistent with one of the most important principles of modern electrical engineering: If a system uniformly samples an analog signal at a frequency that exceeds the highest frequency of the signal by at least a factor of two, the original analog signal can be perfectly recovered from the discrete values produced by sampling.

So what's the squeeze theorem? The Nyquist–Shannon sampling theorem provides a sufficient condition for the sampling and reconstruction of a band-limited signal. Samplingsteorin Nyquist av M Lundin — The Nyquist-Shannon Sampling Theorem. 3.

Nyquist theorem

Observatory The Nyquist Theorem, that says we can't record signals of more than half the sample rate, is actually a guideline. In other areas of information Why only digital ?? ▷ Bandlimited analog signals can be (almost) exactly represented in digital form (Nyquist-Shannon sampling theorem). We cover the sampling theorem (Nyquist), resolution bandwidth, frequency spectrum distortions like aliasing and leakage and how to apply windows in a Nyquist theorem maximum data rate. Garde Med Kort, Og Afbildninger. Borlnge, Sweden.

To explain Nyquist's theorem a bit more: in its most basic form, Nyquist’s work states that an analog signal waveform can be converted into digital by sampling the analog signal at equal time intervals.

nyquist (sys) creates a Nyquist plot of a dynamic system sys. The sampling theorem, which is also called as Nyquist theorem, delivers the theory of sufficient sample rate in terms of bandwidth for the class of functions that are bandlimited. The sampling theorem states that, “a signal can be exactly reproduced if it is sampled at the rate fs which is greater than twice the maximum frequency W.” The Nyquist Theorem. In 1928 Harry Nyquist, who was a researcher for AT&T, published the paper “Certain Topics in Telegraph Transmission Theory.” He described a way to convert analog signals into digital signals that would more accurately transmit over telephone lines.

Nyquist theorem then states that if we were to sample this signal we would need samples with a frequency larger than twice the maximum frequency contained in the signal, that is f sample 2f max: (2) If this is the case, we have not lost any information during the sampling process and we could theoretically reconstruct the original signal from the sampled
