Abstract
In a method for suppression of even-numbered harmonic distortion which occurs in a non-linear elementa signal x(n) is linked to a pseudo random noise sequence r(n), and is thus spread, before passing through the non-linear elementAfter passing through the non-linear elementthe signal y*(n) is once again linked to the pseudo random noise sequence r(n). The signal y*(n) is thus despread while, in contrast, even-numbered order harmonic elements are once again spread, and remain as broadband noise.
