The Nyquist Limit’s tracks Xemnu The Titan by The Nyquist Limit published on 2016-09-01T16:41:48Z This limit is called the Nyquist limitof a given sampling frequency. Sine wave at 1/2 sampling rate with two samples per cycle If a sine wave higher than the Nyquist frequency is sampled, a sine wave of lower frequency results. This effect is called aliasing.

Nyquist Limit The absolute limiting resolution of a sensor is determined by its Nyquist limit. This is defined as being one half of the sampling frequency, a.k.a the number of pixels/mm (Equation 3). For example, the Sony ICX285 is a monochrome CCD sensor with a horizontal active area of 9mm containing 1392 horizontal pixels each 6.45μm in size. Pulsed ultrasound doesn’t have a particular upper limit for displaying the Doppler shift. It’s commonly known as the Nyquist limit.
Nyquist frequency - twice the maximum frequency occurring in the transmitted signal telecom, telecommunication - systems used in transmitting 2005-06-26 What is Nyquist limit in ultrasound? The Nyquist limit defines the frequency at which aliasing and range ambiguity will occur, and is equal to the PRF/2. Factors such as higher velocities of target structures and increasing depth of the region of interest insonated will result in aliasing and consequent range ambiguity.
