ABSTRACT:
A signal interpolator comprises a fractional interpolator and a numeric controlled oscillator. The numeric controlled oscillator may generate a control signal for controlling the fractional interpolator. The numeric controlled oscillator generally comprises a register, a modulo-M device, and an adder. The register may hold a count value, and the modulo-M device may apply a modulo-M function to the count value to generate the control signal therefrom. The adder may add an increment value to the modulo-M signal from the modulo-M device, to update the count value in the register.
