Lecture 20: Discrete Fourier Transform
Learn the properties and applications of the DTFT and the DFT two common methods for analyzing signals in the frequency domain See examples of how to use the DTFT to find the DFT of a shifted delta function and a cosine and how to use the DFT to find the DTFT of a cosine |
How do you calculate symmetry properties of DFT?
Let us take two signals x 1n n and x 2n n, whose DFT s are X 1ω ω and X 2ω ω respectively. So, if Then ax1(n) + bx2(n) → aX1(ω) + bX2(ω) a x 1 ( n) + b x 2 ( n) → a X 1 ( ω) + b X 2 ( ω) where a and b are constants. The symmetry properties of DFT can be derived in a similar way as we derived DTFT symmetry properties.
