Propose a method that would allow estimation of the Rayleigh limit experimentally. By using Matlab implementation of your method, prove (or disprove) that the theoretically derived equation is correct for a rectangular window. Repeat similar experiments for another time window (say, for Kaiser or Hamming window) to obtain Rayleigh limit of frequency resolution for it. Are your observations consistent? Hint: in your method, please, note that the formula is valid "about half of the time".
