WebMay 4, 2024 · 0. When taking the FFT of a signal, we need to decide on the amount of points. The more points we have, the higher our frequency resolution is. This is our "fft poitns" - the amount of points in the FFT. A 2 point fft would have to sample inputs and two frequency bins. A 2024 point FFT would take 2024 points on the input and output 2024 ...
