Explain Inverse Discrete-Time Fourier Transform
1. Observe the same things among this formula and the inverse analogue Fourier transform:
2. The range of integration is just now -π to π rather than -∞ to ∞. (π corresponds to half the sampling frequency).
3. Negative frequencies are once again included.
4. With the DTFT, the forward transform is a summation and the inverse transform is an integral. This is because {h[n]} is a sequence whereas H(ej?) is a function of the continuous variable ?.
