Patent DE-2856752-A1 (DE)
Inventor: MEYRAT PIERRE DR
IPC: H04J1/20
Filed: 1978-12-29
Abstract: To reduce the effects of certain mutual interferences between the information transmission channels, carrier frequencies are used which are coupled to one another in such a manner that each carrier frequency fn satisfies the equation fn = fI + n.fII (fI and fII equals a predetermined frequency values and n = integral number). Because of this mutual coupling of the carrier frequencies, there is a risk that very high aggregate amplitudes can occur depending on the mutual phase relationships of the various carriers. This is why the phase of each carrier is swept, for example with a sweep signal with a frequency in the range from 0.2 to 10 Hz. The result is that the signals of the information transmission channels are not added together with respect to voltage but only in accordance with a power addition which reduces the amplifier modulation and interference amplitudes.
