<p>For correcting a signal distortion, the use of a predistortion network is known. It generally comprises a harmonic generator and a filter for modifying the phase of the correction signal as a function of the frequency. To facilitate the construction of this assembly, the harmonic generator comprises a divider/phase shifter (47) which produces two anti-phase signals; between the outputs of the divider/phase shifter (47) are connected two diode pairs (62-63 and 64-65); the common points of the two diodes of each pair are connected to the input of a symmetrical filter (66-70).</p> |
