ABSTRACT:
A digital noise shaper circuit is provided which includes a signal transfer function and a noise transfer function, with associated coefficients and gain scaling factors, which ensures a predetermined frequency response, signal passband and noise stopband, and which converts a multi-bit digital signal to a 1-bit digital signal.
