DIGITALER PHASEN- UND AMPLITUDENMODULATOR, UND VERFAHREN DAZU

A method and a circuit for modulating a carrier signal (Se) with a signal (SCj) having at least a modulation cell (CMi) by phase shift for receiving two digital control signals (Scji, SCji2) representing at least part of the digital modulation signal (SCj). For at least a value of the digital modula...

Zusammenfassung:A method and a circuit for modulating a carrier signal (Se) with a signal (SCj) having at least a modulation cell (CMi) by phase shift for receiving two digital control signals (Scji, SCji2) representing at least part of the digital modulation signal (SCj). For at least a value of the digital modulation signal (SCj), the method consists in applying on at least a common modulation cell (CMi), two digital control signals (SCji1, SCji2) of identical value, the modulation cell (CMi) delivering a signal, called a modulated elementary signal (Ssi), which is null for the digital modulation signal value (SCj).
