WebWith an FFT based spectrum analyzer, the frequency resolution is = /, the inverse of the time T over which the waveform is measured and Fourier transformed. With Fourier transform analysis in a digital spectrum analyzer, it is necessary to sample the input signal with a sampling frequency ν s {\displaystyle \nu _{s}} that is at least twice the ... WebFFT based would also assume precise placement of the elements and equivalent delays for all legs from the sensor to the digitizer. The analysis breaks out things like eigenvectors and eigenvalues to select the signal of interest and applies a weighting vector to the incoming feed to minimize interference sources. It’s been 20 years since I ...
