Give The Properties Of One-dimensional Dft?

1.	Give The Properties Of One-dimensional Dft?
Answer» The DFT and unitary DFT matrices are symmetric. The EXTENSIONS of the DFT and unitary DFT of a SEQUENCE and their inverse TRANSFORMS are periodic with period N. The DFT or unitary DFT of a real sequence is conjugate symmetric about N/2.
