nyquist frequency Sentence Examples
- The Nyquist frequency, half of the sampling rate, limits the highest frequency that can be accurately represented in a digital signal.
- To prevent aliasing, the sampled data's Nyquist frequency must exceed twice the highest frequency component in the original signal.
- Data acquired at a rate below the Nyquist frequency will result in frequency aliasing, potentially misinterpreting high-frequency components.
- The Nyquist frequency is crucial in determining the sampling rate necessary for accurate signal reproduction.
- Reconstructing a continuous-time signal from its sampled version is possible if the sampling frequency exceeds the Nyquist frequency.
- Oversampling beyond the Nyquist frequency provides a safety margin to minimize aliasing risks and improve signal fidelity.
- In image processing, the Nyquist frequency determines the maximum spatial frequency that can be captured without aliasing artifacts.
- Ultrasonic imaging relies on carrier frequencies exceeding the Nyquist frequency to accurately depict high-frequency details.
- Multi-rate digital signal processing techniques involve converting signals between different Nyquist frequencies.
- The Nyquist criterion serves as a fundamental guideline for signal acquisition and analysis to ensure accurate representation and prevent frequency distortion.
