ABSTRACT:
In a noise shaping requantization circuit, a requantized output digital signal and an input digital signal are processed in an operational circuit whose output signal is requantized to provide the requantized output signal. The processing circuit can be configured in a variety of ways but has fixed limitations established for circuit parameters which determine the relationship between the output signal therefrom and the two input signals. By comparison with prior art noise shaping requantization circuits, a substantially better S/N ratio (assuming equal values of output signal resolution), or a substantially lower degree of output signal resolution (assuming equal values of S/N ratio) can be achieved, with stable operation.
