<math display="block">\mathbf{Y} = 2(\mathbf{X}\circ \mathbf{F})\mathbf{E} </math>
where <math>\circ</math>represents the element-wise multiplication operator.
The amplitude of each frequency component can be determined by calculating the absolute value of <math>\mathbf{Y}</math>, which is a complex quantity. The phase of <math>\mathbf{Y}</math>an be found using the complex argument of <math>Y</math>
