Featured tools from the Family registry.
- Discrete Fourier Transform Calculator Compute DFT, inverse DFT, FFT and IFFT for real or complex sequences up to 64 samples. Compare all bins, inspect magnitudes, share inputs and export results.
- DFT Calculator Compute the direct DFT for real or complex sequences of 1–64 samples. Inspect every frequency bin and magnitude, share precise inputs and export full results.
- FFT Calculator Compute radix-2 FFT for real or complex sequences with power-of-two lengths up to 64. Inspect all frequency bins, share inputs and export complete results.
- Laplace Transform Calculator Evaluate eight causal Laplace pairs or their inverse with real inputs. See formulas, ROC limits, numerical warnings, graphs and shareable results.
- Z Transform Calculator Evaluate eight causal Z-transform pairs or inverse sequences. Check real inputs, ROC limits, formulas, numerical warnings, graphs and shareable results.
