Wikipedia and other references say the power spectrum. Isn't that the square of the Fourier transform? The FFT produces an "amplitude spectrum" and then you square that to get a "power spectrum"?

WebIn the above bend allowance formula, except for sheet metal k-factor and bend allowance values, all other values are known. Therefore to calculate the value of the k-factor firstly we need to calculate the value of bend allowance. The value of a bend allowance for a material can be calculated using an experiment in the following steps. Step-1 WebFlatness, which regulates the deviation from the geometrically perfect plane, is measured using a dial gauge or a coordinate measuring machine.
