The text explaining the FFT can be consolidated to one page, rather than duplicating it. Linking to Wikipedia for general background on FFT is good. Maybe on Tekwiki we just need to explain the specific aspects as they pertain to these instruments, how they are used, how they work, limitations, etc.
Kurt, okay, I'll review each of the Fourier Analyzers pages and make the appropriate changes. --Jyohe (talk) 19:26, 16 July 2019 (PDT)
