This tool helps you quickly calculate the Fast Fourier Transform of your data.
How to use the FFT Calculator:
To use the Fast Fourier Transform (FFT) calculator, follow these steps:
- Enter the sampling rate in Hertz (Hz). This is the rate at which the signal was sampled.
- Input the total number of samples you have.
- Provide the sampled values in a comma-separated format.
- Click the “Calculate” button to perform the FFT calculation and view the results in the table below.
How it calculates:
The FFT calculator takes the sample values and computes their frequency components using the Fast Fourier Transform algorithm. It outputs the frequency (in Hz) and the corresponding magnitude for each calculated frequency.
Limitations:
- The input samples must be numerical values and the total number of samples must match the count specified.
- If the number of samples provided is not a power of 2, the accuracy of the FFT calculation may be compromised. Currently, samples count should match exactly to be processed.
