Raw fft
WebTo report FFT performance, we plot the " mflops " of each FFT, which is a scaled version of the speed, defined by: mflops = 5 N log 2 (N) / (time for one FFT in microseconds) for complex transforms, and. mflops = 2.5 N log 2 (N) / (time for one FFT in microseconds) … WebI have a quick question on performing angle FFT (anlge estimation) from raw data. I was using DCA1000 and IWR1642 with setting of 1 TX and 4 RX. I understand how to perform the range FFT and doppler FFT from the raw data. I also learned that to perform the angle FFT …

You can compare the fft of the filtered data to the fft of the raw data to see the filtering effect. If you divide element-wise the fft of the filtered data by the fft of the raw data you will get the effective transfer function of the sgolayfilt filter. That will help you understand how it works. .
