Al-Janabi, Mohammed, Kale, Izzet and Morling, Richard C.S. (1999) Application of fractional delay filters to tune the centre frequency location of single-band sigma-delta modulators.

This paper presents a novel technique for the design of narrow-band sigma-delta modulators with an embedded tunable centre frequency mechanism. This method demonstrates that the use of sum filters combined with a fractional delayer provide the flexibility of tuning the noise shaping band for any desired variable centre frequency input signal.
