ABSTRACT:
Digital signal transmitter devices mostly present a distinct wide-band interference spectrum which renders compliance with the presently applicable EMC standards substantially more difficult.Available provisions for improving the EMC characteristics take an influence on the quality in transmission and on the immunity to interference.By the inventive method the carrier signal or output signal, respectively, of the transmitter is so modulated that the narrow spectral lines are spread and the spectral power density is reduced.
