Patent ID: 8416880

Claim:
A digital modulator, comprising: at least one input terminal configured to receive at least one signal, a symbol generating unit comprising a first output terminal and at least a second output terminal, wherein the symbol generating unit is configured to generate a first symbol waveform for the first output terminal depending on the received signal, and wherein the symbol generating unit is configured to generate at least a second symbol waveform for the second output terminal depending on the received signal, wherein the first symbol waveform comprises at least one different parameter value compared to the second symbol waveform, at least one third output terminal connectable to at least one of the first output terminal and the second output terminal via a switching unit, a controlling unit configured to control the switching unit depending on the received signal such that a modulated output signal is generated, and a sequence controlling unit configured to control the sequence of communication establishing of the switching unit depending on at least one of the current received signal and the next received signal to smooth a transition from one duty cycle or phase to a next duty cycle or phase by first closing the switching unit with a small coarse duty cycle waveform and next closing the switching unit with a large coarse duty cycle.
