WebNov 24, 2024 · 1 Answer. No. An FFT will propagate any unknown input to every output. This because in a transform such as a DFT, every output value directly depends on every input value, and thus can not be computed without known values for every input. Or, an alternate answer is Yes: If any input to an FFT is an NaN, just output the FFT result as an ...
