Spectral Analysis Tool - Texas Instruments ADS8900BEVM-PDK User Manual

ADS8900BEVM-PDK Operation
Finally, the FFT tool includes windowing options that are required to mitigate the effects of non-coherent
sampling (this discussion is beyond the scope of this document). The 7-Term Blackman Harris window is
the default option and has sufficient dynamic range to resolve the frequency components of up to a 24-bit
ADC. Note that the None option corresponds to not using a window (or using a rectangular window) and is
not recommended.
