RECURSIVE BIT-STREAM CONVERTER AND METHOD FOR RECURSIVE BIT-STREAM CONVERSION

摘要

Recursive bit-stream converter (Rebic) for converting a multi-bit digital input signal to a single bit digital output signal comprising a digital low pass filter and multi-bit quantizer means in a feedback arrangement and means to serialize the digital words of the quantizer means. To obtain a non-integer Rebic factor the quantizer means comprise at least two quantizers that are successively operative to serialize their digital words to the output of the converter.
