Result
44.1 kHz sampling gives a 22.05 kHz Nyquist frequency, comfortably above an 18 kHz signal. A 30 kHz component would alias down to 14.1 kHz and be indistinguishable from real content.
How Calculateur Échantillonnage Nyquist works
- Open Calculateur Échantillonnage Nyquist and review the example state before entering your own values.
- Enter or select the information needed for Calculateur Échantillonnage Nyquist.
- Review the result and adjust the inputs if you want to compare another case.
Calculate the minimum sample rate for a signal bandwidth, the resulting Nyquist frequency, and what aliasing does when you fall below it. The interactive workspace runs in your browser, so you can review the result without creating an account.
