If you have a variable-frequency signal source, another way to observe aliasing is to adjust the frequency slowly while watching
the spectral display. If some of the harmonics are aliased, you will see the harmonics decreasing in frequency when they should
be increasing or vice versa.
Blackman-Harris FFT window concepts
FFT windows have various resolution bandwidths and scallop losses (see the figure below). Choose the one that best allows you
to view the signal characteristics you are interested in.
The Blackman-Harris window has a low amount of energy leakage compared to the other windows. Its best use is for single
frequency signals to look for higher order harmonics.
