Lecture 11: Discrete-time Fourier transform

ocw.mit.edu

the Fourier transform gets us back to the original signal, time-reversed. In discrete time the situation is the opposite. The Fourier series represents a pe-riodic time-domain sequence by a periodic sequence of Fourier series coeffi-cients. On the other hand, the discrete-time Fourier transform is a representa-

The function F(k) is the Fourier transform of f(x). The inverse transform of F(k) is given by the formula (2). (Note that there are other conventions used to deﬁne the Fourier transform). Instead of capital letters, we often use the notation f^(k) for the Fourier transform, and F (x) for the inverse transform. 1.1 Practical use of the Fourier ...

• Fourier Series: Represent any periodic function as a weighted combination of sine and cosines of different frequencies. • Fourier Transform: Even non-periodic functions with finite area: Integral of weighted sine and cosine functions. • Functions (signals) can be completely reconstructed from the Fourier domain without loosing any ...
