Abstract:
A converter for converting an input signal from a first format to a second format, the converter comprising:a decomposition section; a converter array operatively coupled to the decomposition section; and a recombination section operatively coupled to the converter array; wherein the decomposition section includes: an input to receive the input signal; a splitter to divide the input signal into a plurality of signals; a plurality of signal outputs, each of which provides as an output one of the plurality of signals; and a clock circuit having a plurality of clock outputs with relative phase delays for providing sample clocks to the converter array; wherein the converter array includes a plurality of converters, each of the converters having a signal input to receive one of the plurality of signals, a clock input to receive one of the sample clocks and an output that provides a converted signal; wherein at least one of the decomposition section and the recombination section includes filters for filtering either the plurality of signals or the plurality of converted signals; and wherein at least one of the filters includes an amplitude attenuator.
