Nyquist Rate Calculator

Compute the minimum sampling rate fs = 2·f_max.

Input Data

Input Max frequency f_max.
Hz

Results

40,000Hz
Nyquist rate fs = 2·f_max.

At a glance:Nyquist Rate Calculator: enter parameters to compute results; complements related calculators.

Formula

fs ≥ 2 · f_max (sampling theorem).

How to Use

  1. Enter the max frequency.
  2. It returns the minimum sampling rate.

Case Studies

Speech 20 kHz → 40 kHz

CD sampling 44.1 kHz exceeds this.

FAQ

Below it?

Below Nyquist rate causes aliasing — high freq folds into false low freq.
