Fold a supplied signal frequency into the first Nyquist band and show the folding curve. Provide Sampling rate (Hz), Signal frequency (Hz) to compute results directly in your browser. For real uniformly sampled signals, folded frequency = min(f mod fs, fs − (f mod fs)). Nyquist is fs/2; exact zone boundaries are assigned upward. The diagram shows the ideal frequency-folding relation, not a measured spectrum. Numeric output uses up to 12 significant digits; floating-point rounding can occur.

How the Aliasing Frequency Calculator Works & Core Formula
The Aliasing Frequency Calculator evaluates Sampling rate (Hz), Signal frequency (Hz) in client-side JavaScript using the deterministic rule below and updates the output panel immediately without uploading data to a server.
Fold a supplied signal frequency into the first Nyquist band and show the folding curve.
For real uniformly sampled signals, folded frequency = min(f mod fs, fs − (f mod fs)). Nyquist is fs/2; exact zone boundaries are assigned upward. The diagram shows the ideal frequency-folding relation, not a measured spectrum. Numeric output uses up to 12 significant digits; floating-point rounding can occur.
Aliasing Frequency Calculator Quick Reference & Input Guide
Review the input parameters, allowed value ranges, and worked reference cases for the Aliasing Frequency Calculator below before running your calculation.
| Parameter / Scenario | Default / Sample Value | Rule or Allowed Range | Output / Usage Note |
|---|---|---|---|
| Input: Sampling rate (Hz) | 1000 | Range: 1e-09 to 1000000000.0 | Required workspace parameter |
| Input: Signal frequency (Hz) | 700 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Worked Case 1: Baseline run (Sampling rate (Hz) = 1000) | Preloaded / test values | Fold a supplied signal frequency into the first Nyquist band and show the folding curve | Sampling rate (Hz) = 1000; Signal frequency (Hz) = 700. Output: Folded frequency: 300 Hz; Nyquist frequency: 500 Hz; Nyquist zone (boundary assigned upward): 2. |
| Worked Case 2: Comparison scenario (aliasing frequency formula) | Preloaded / test values | Fold a supplied signal frequency into the first Nyquist band and show the folding curve | Sampling rate (Hz) = 1000; Signal frequency (Hz) = 1500. Output: Folded frequency: 500 Hz; Nyquist frequency: 500 Hz; Nyquist zone (boundary assigned upward): 4. |

Practical Worked Examples for Aliasing Frequency Calculator
These concrete scenarios illustrate how the Aliasing Frequency Calculator processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Sampling rate (Hz) = 1000)
Sampling rate (Hz) = 1000; Signal frequency (Hz) = 700. Output: Folded frequency: 300 Hz; Nyquist frequency: 500 Hz; Nyquist zone (boundary assigned upward): 2.
Comparison scenario (aliasing frequency formula)
Sampling rate (Hz) = 1000; Signal frequency (Hz) = 1500. Output: Folded frequency: 500 Hz; Nyquist frequency: 500 Hz; Nyquist zone (boundary assigned upward): 4.
Boundary & unit check (Aliasing Frequency Calculator)
When solving for 'aliasing frequency calculator', verify that Sampling rate (Hz), Signal frequency (Hz) use consistent units and stay within the documented scope: For real uniformly sampled signals, folded frequency = min(f mod fs, fs − (f mod fs)). Nyquist is fs/2; exact zone boundaries are assigned upward. The diagram shows the ideal frequency-folding relation, not a measured spectrum. Numeric output uses up to 12 significant digits; floating-point rounding can occur.
How to Read and Verify the Aliasing Frequency Calculator Output
The output panel reports the exact result derived from Sampling rate (Hz), Signal frequency (Hz) alongside any unit or formatting notes.
Every calculation follows the rule: Fold a supplied signal frequency into the first Nyquist band and show the folding curve. Because JavaScript uses IEEE 754 double-precision floating-point arithmetic, numeric outputs display up to 12 significant digits where applicable.
Always cross-check the displayed result against the scope note (For real uniformly sampled signals, folded frequency = min(f mod fs, fs − (f mod fs)). Nyquist is fs/2; exact zone boundaries are assigned upward. The diagram shows the ideal frequency-folding relation, not a measured spectrum. Numeric output uses up to 12 significant digits; floating-point rounding can occur) before applying the value to production specifications, financial models, or lab records.
