FFT spectrum frequency resolution calculator

Calculate the frequency resolution of a FFT spectrum using this online calculator - formula included.

TechOverflow calculators:
You can enter values with SI suffixes like 12.2m (equivalent to 0.012) or 14k (14000) or 32u (0.000032).
The results are calculated while you type and shown directly below the calculator, so there is no need to press return or click on a Calculate button.
