So, my understanding of this material is that X(f),X1(w) mainly differ on their X axis scaling, and same sort of thing X1 and X2?
Valid? ~AJFunche
- It's a bit more complicated than a mere rescaling of the frequency axis. First, one must not forget that the DTFT is ALWAYS periodic with period $ 2\pi $. Second, the amplitude of the FT changes when sampling. Third, something called "aliasing" might occur. Can other students please try clarify this? I will step in if I notice obvious misconceptions/mistakes.--Mboutin 08:56, 7 September 2010 (UTC)
