Abstract
A 1-bit signal processor receives a 1-bit signal having a first sampling rate eg 64 fs. An upconverter (,) increases the sampling rate to eg 128 fs. A series of Delta Sigma Modulators (,) processes the signal. The processed signal is down-converted by a converter (,) to 64 fs. As least the Delta Sigma Modulators may be implemented on an integrated circuit. The down-converter is arranged to prevent noise being folded back into the signal band.
