Abstract
A system for converting a digital input signal into an analog output signal is provided, the system has at least three different signal paths with different but overlapping frequency ranges, at least three digital-to-analog converters, at least three analog filters, and a combiner unit. Each of the digital-to-analog converters is connected to at least one signal path, wherein the signals transmitted to the digital-to-analog converters are phase coherent. Each of the digital-to-analog converters is connected to a combiner unit, and each of the analog filters is associated with one of the digital-to-analog converters, wherein at least one of the digital-to-analog converters has a lower sampling rate than the sampling rate of at least two others of the digital-to-analog converters. Further, a method for converting a digital input signal into an analog output signal is shown.
