sigma delta modulator tutorial for pll

Can I implement the spread spectrum function using Sigma-Delta PLL? How?

TIA.

pll delta sigma modulator

we r implementing freq modulation and demodulation using pll so i feel we can implement spread spectrum like freq hop spread spectrum

we can vary divider ratio by using PN generator and sigma delta modulator

sigma delta modulator use in pll

You can also take a look at the Synthesizer course notes on Professor P.Allen's website at Georgia tech.

can you upload the course?
