The Nyquist bandwidth is defined to be the frequency spectrum from dc to fs/2. The frequency spectrum is divided into an infinite number of Nyquist zones, each having a width equal to 0.5fs as shown. In practice, the ideal sampler is replaced by an ADC followed by an FFT processor.
What is a Nyquist Zone? The Poisson summation formula indicates that the samples of function x(t) are sufficient to create a periodic extension of function X(f).
Nyquist frequency - Wikipedia
In signal processing, the Nyquist frequency (or folding frequency), named after Harry Nyquist, is a characteristic of a sampler, which converts a continuous function or signal into a discrete sequence.
Nyquist–Shannon sampling theorem - Wikipedia
The Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing.
Every Fs/2 zone starting from DC to Fs/2 is called the Nyquist Zone. The first Nyquist Zone is from DC to Fs/2, the second Nyquist Zone is from Fs/2 to Fs, and the third Nyquist Zone is from Fs to 3Fs/2, and so on. Figure 1. Normal Sampling (Oversampling) Case: IF Frequency in the Center of Nyquist Zone.
SSZTCF7 Technical article | TI.com - Texas Instruments
The first Nyquist zone represents the maximum sample bandwidth, which is equal to the sampling rate, Fs, divided by two. The higher Nyquist zones represent the adjacent spectrum bands with equivalent bandwidth.
Nyquist Sampling - AstroBaki - University of California, Berkeley
Feb 5, 2021 · If you sample your signal at, or above, the Nyquist rate (also known as “Nyquist sampling” the signal), you can reconstruct the signal. If you don’t, you’ll have to deal with aliasing, which is described below.
Multi-Nyquist Zones Operation-Solution Note - Tabor Elec
Traditionally, DACs analog BW is not much higher than the BW of its first Nyquist zone causing the suppression of signals at higher Nyquist zones. The new DAC used in the Tabor Signal Expert series offers an exceptionally wide bandwidth reaching up to 7GHz and even beyond.
Frequency Folding Tool | Design Center | Analog Devices
Frequency Folding Tool. This tool illustrates the aliasing effects of an input signal and its harmonics when digitized by an ADC. The user can select single tone or a modulated carrier input signal and can observe aliasing in up to 10 Nyquist zones.
