ABSTRACT:
A digital signal processing system utilizes an internal filter of a delta-sigma modulator in a novel manner to implement both the integration functions of the delta-sigma modulator and a decimation function. Using the internal filter to combine integration and decimation functions can eliminate the need for a separate decimation filter. The combination of integration and decimation functions can also improve signal-to-noise ratio by improving low-pass filtering performance.
