NCO Problems

Can I implement this form of sequence with NCO,S(nT)=Asin(2πfn²T),That is, whether the phase increment changes along each clock hop.

Thank you in advance for your help.

Can you explain what is meant by NCO here ? if you would like to implement sine function you can implement vai sine look up table stored in Intrnal RAM and apply to the logic accordinly.

Just had a chance to look at IP core ; looks like it is possible using NCO to generate the sine in terms of pulsed sine .

Kindly let me know if you have any question further for the same ?

It means that NCO IP core can implement the form S(nT)=Asin(2πfnT), but it's not certain that S(nT)=Asin(2πfn²T) in this case.
