A method is presented and illustrated for numerical examination of the processing of a multifrequency signal in a UHF electron - beam device, which extends various existing particular approaches in the theory of multifrequency nonlinear processes. The input spectrum may consist of several components separated by some fundamental frequency, and each of the components in turn may contain numerous spectral lines similar in frequency. The flux is replaced by a discrete model composed of charged elements. The equations of the nonlinear theory are written in terms of a method based on separate consideration of the vortex and Coulomb fields.
