In my system we have the following.

$$V_{in}=1+\cos(2\pi 900,000)$$ $$V_{sample}=V_{in}-0.01V_{in}^2$$ $$V_{noise}=200 \times 10^{-6}V$$ After the input i get in $V_{sample}$ the following coefficients of harmonics in the output as shown in the calculation bellow: Cos_theta :0.98 Cos_2theta :-5*10^-3 DC:non relevant My question is regarding the SNDR do i need to divide both the voltage of the signal and the voltage of the hormonic distortion by $\sqrt{2}$ doing RMS on each harmonic?
