nyquist rate Sentence Examples
- The Nyquist rate determines the maximum frequency that can be accurately represented in a digital signal.
- A sampling rate higher than the Nyquist rate avoids aliasing, where higher frequencies appear as lower ones.
- The Nyquist rate for a given signal depends on the highest frequency component present in the signal.
- Oversampling beyond the Nyquist rate can provide improved signal-to-noise ratio and better filtering capabilities.
- Signal processing techniques like anti-aliasing filters are used to prevent frequency components from exceeding the Nyquist rate.
- In digital audio systems, the Nyquist rate is usually twice the highest audible frequency, which is 22,050 Hz for high-quality recordings.
- The Nyquist rate sets a limit on the bandwidth of analog signals that can be transmitted or stored digitally.
- Modern telecommunication systems often employ Nyquist sampling techniques to maximize bandwidth utilization.
- The Nyquist rate is a fundamental concept in digital signal processing, providing a way to represent analog signals accurately in the digital domain.
- Advances in signal processing and data acquisition have allowed for sampling rates approaching the Nyquist rate with high precision.
