Sampling Rate Calculator
Enter the known values and run the calculation.
Enter the sampling rate in hertz and run the calculation.
The result reports the Nyquist frequency in hertz.
Overview
Estimate Nyquist relationships and sampling requirements for digitized signals.
Use this tool to report the Nyquist frequency for a stated sampling rate.
Use it for DAQ planning, audio setup, and quick checks when you need the highest ideal frequency a sampling system can represent.
The math and how it's used
The Nyquist frequency is the highest frequency that can be represented without aliasing in the ideal textbook case.
Meeting Nyquist numerically is not the same thing as having enough anti-alias filtering or measurement margin.
This is a planning number for acquisition work: it tells you the textbook Nyquist boundary tied to the sample rate you picked.
It does not guarantee a clean measurement by itself. Front-end bandwidth, anti-alias filtering, and guard band still decide whether the sampled result is trustworthy.
What to watch
Nyquist is only the first condition. Real measurements still need analog bandwidth margin and anti-alias filtering ahead of the converter.
If the signal is not band-limited, content above Nyquist can still fold back into the observed band.
