Abstract:
1. A transmitter, comprising: a digital-to-analog converter for converting a digital signal into an analog signal; a first switch arranged for inputting, in a first-type operating mode of said transmitter, a first digital signal into said digital-to-analog converter to obtain a first analog signal, and for inputting, in a second-type operating mode of said transmitter, a second digital signal into said digital-to-analog converter to obtain a second analog signal; a first-type unit for generating a first-type modulated signal in dependence on at least said first analog signal; a second-type unit for generating a second-type modulated signal in dependence on at least said second analog signal, and a second switch arranged for inputting, in said first-type operating mode, said first analog signal into said first-type unit, and for inputting, in said second-type operating mode, said second analog signal into said second-type unit.
