The following represents some part of my equation, which describes sine functions in discrete domain.
y[n] = sin(2*pi*f0*n*dTs) * sin(2*pi*f0*n*Ts)
where f0 is the frequency of sine, and n variable is an integer number, n=[1:N] (e.g., N=64k).
dTs and Ts are sampling periods and they have the relationship: dTs << Ts.
Then, I have to approximate "sin(2*pi*f0*n*dTs)" among the following equation. Actually, I'm looking for a way to remove n from "sin(2*pi*f0*n*dTs)" by calculation approximation. Please help me out. This is very important for me.
