WebFeb 17, 2024 · So for an FFT size of 256, you can send in the 4 values (as you do currently), but 64 samples in at a time. The valid input signal will also need to be 64x1. In turn, you will get 64 output values for each call. The simplest way to do this is by use of a Buffer block before each input. WebFFT_N = dsphdl.FFT returns an HDL FFT System object, FFT_N, that performs a fast Fourier transform. example. FFT_N = dsphdl.FFT (Name,Value) sets properties using one or more name-value pairs. Enclose each property name in single quotes. Example: fft128 = dsphdl.FFT ('FFTLength',128)
WebHDL-optimized FFT will have latency in its output. When you compare your results you need to account for this latency. Except for latency it should match the FFT results. I would expect Spectrum Analyzer to have an internal buffer and then compute the spectrum when the buffer is full. Navan Daniel Yang 5 years ago ...
