- Input frequencies (Hz)
- 10,70,130
- Sampling frequency (Hz)
- 100
- Folded frequency magnitudes (Hz)
- [10,30,30]
- Aliased input count
- 2
Try another scenario
- Input frequencies (Hz)
- [5, 90, 250]
- Sampling frequency (Hz)
- 100
- Folded frequency magnitudes (Hz)
- [5,10,50]
- Aliased input count
- 2
Calculation method
Calculation method
Folded frequency magnitudes (Hz)
Fold each input into [0, sample rate/2].
Aliased input count
Count inputs strictly above Nyquist.
Symbols and units
- a
- Input frequencies (Hz)
- b
- Sampling frequency (Hz)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Input frequencies, sampling rate. Returns Aliased frequencies under chosen convention. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Input frequencies (Hz): minimum 0, maximum 1000000000000.0. Sampling frequency (Hz): minimum 1e-12, maximum 1000000000000.0.
