Analysis of information sources in references of the Wikipedia article "Tần số Nyquist" in Vietnamese language version.
The Nyquist frequency is that frequency whose period is two sampling intervals.

Frequencies "fold" around half the sampling frequency - which is why [the Nyquist] frequency is often referred to as the folding frequency.Quản lý CS1: khác (liên kết)
