snr and sndr

SNR: Signal to noise ratio. It's the ratio of signal level to noise level. No non-linearities included in this measurement

SNDR: Signal-to-noise + distortion ratio. It is the ration of signal power to (noise power plus spuriouse harmonics power). These spurious harmonics are those appearing to circuit non-linearity.

SFDR: Spurious free dynamic range. The dynamic range through which no non-linearity exists.

Hope this helps

I think you can compare only between SNR and SNDR. Usually SNR would be larger than SNDR since the spurs have much larger power than noise (Spurs are deterministic tones resulting from nonlinearities as opposed to the distributed noise power)
