It must be noted that the number of shift-in and shift-out cycles is equal to the number of flip-flops that are part of the scan chain. For a scan chain with, let’s say, 100 flops, one would require 100 shift-in cycles, 1 capture cycle and 100 shift-out cycles. csi bittersweet castThe discrete Fourier transform is an invertible, linear transformation $${\displaystyle {\mathcal {F}}\colon \mathbb {C} ^{N}\to \mathbb {C} ^{N}}$$ with $${\displaystyle \mathbb {C} }$$ denoting the set of complex numbers.
