ABSTRACT:
Embodiments of a signal processing system, a method, and fractionally modulated digital delay lines are generally described herein. Other embodiments may be described and claimed. In some embodiments, a fractional address is generated by adding a delay value to a fractional offset value, and input sample values are interpolated based on a fractional portion of the fractional address. A write operation may be performed to the integer portion of the fractional address for each sample period using the interpolated input sample values. Adjusted addresses may be generated when addresses are either skipped of duplicated.
