WebAug 15, 2024 · You get 32 real and 32 imaginary outputs because you are using a complex to complex FFT. Remember that you've converted your 32 samples into 64 values (or 32 complex values) by extending it with zero imaginary parts. This results in a symetric FFT output where the frequency result occurs twice. WebMar 29, 2024 · The ‘filtering’ step requires that you define the characteristics you want for the filter, and then design it, and filter your signal. You can filter it in the frequency-domain with the fftfilt (link) function, however it requires that you give it a finite-impulse-response or FIR filter. There are several ways to design your filter, the easiest being the designfilt (link) …
