It is the extra logic which we put in the normal design, during the design process, which helps its post-production testing. DFT is independent of design ... Web12. Normally a Fourier transform (FT) of a function of one variable is defined as. f k = ∫ − ∞ ∞ f ( x) exp ( − 2 π i k x) d x. This means that f k gets the units of f times the units of x: [ f k] = [ f] × [ x]. For an array of inputs { f n ≡ f ( x n) } of length N the discrete Fourier transform (DFT) is normally defined as.
