Abstract:
1. A transmission device comprising: a first path that receives a first signal comprising useful information and that provides a pulse stream signal, the first path having a switched-mode output stage; a second path that receives a second signal and that provides a phase modulated signal; a mixer that receives the pulse stream signal and the phase modulated signal and provides an intermediate signal to the switched-mode output stage; an error computation unit that provides an error signal representative of an Inband Signal Error of the pulse stream signal, the error computation unit having a linear output stage, the error computation unit including a filter coupled to a second mixer, the filter to provide the Inband Signal Error to the second mixer, and the second mixer to perform an operation on the Inband Signal Error and the phase modulated signal to provide the error signal; and an error correction unit that receives the intermediate signal and the error signal and that provides a transmission signal.
