What does Nyquist theorem actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

Now, try to turn the Nyquist theorem upside down. Alternatively, you can use this theorem and intentionally force a system configuration that aliases or folds back higher frequency signals that occur ...

When electrical engineers hear the name "Nyquist," they think of what Harry Nyquist is best known for: his Sampling Theorem. Evidence of its importance is everywhere. Products like cell phones ...

Sampling All A/D and D/A conversions should obey the Shannon-Nyquist sampling theorem. In short, this theorem dictates that an analog signal must be sampled at a rate (the Nyquist sampling rate) equal ...

Technical Terms Sub-Nyquist Sampling: A method to sample signals at rates below the Nyquist frequency by exploiting signal sparsity.

Dec. 8, 2003--According to Nyquist Sampling Theorem, one of the most important rules of sampling, the highest frequency which can be ...
