Predicting transient crosstalk using an `L´-shape transient spectrum

A simple graphical transient crosstalk prediction method is presented. In this method the amplitude density spectrum of the transient results from a superimposition of two constant density functions, which form an `L´-shape spectrum. The amplitude density and the frequency range of the constituent spectra are easily derived from the transient data. It is shown that the errors connected with this method are significantly smaller than those connected with the widely used method in which the spectrum results from the envelope asymptotes of two sin(x)/x functions
