What is conjugate symmetry?
Conjugate symmetry is an entirely new approach to symmetric Boolean functions that can be used to extend existing methods for handling symmetric functions to a much wider class of functions. These are functions that currently appear to have no symmetries of any kind. Conjugate symmetries occur widely in practice.
How do you find the conjugate symmetry?
A function f(a) is conjugate symmetric if f∗(-a) = f(a). A function f(a) is conjugate antisymmetric if f∗(-a) = -f(a). If f(a) is real and conjugate symmetric, it is an even function. If f(a) is real and conjugate antisymmetric, it is an odd function.
What is symmetry property of Fourier transform?
Symmetry Properties
Represent x(t) as the sum of an even function and an odd function (recall that any function can be represented as the sum of an even part and an odd part). x(t)=xo(t)+xe(t) Express the Fourier Transform of x(t), substitute the above expression and use Euler's identity for the complex exponential.
Does Fourier transform preserve symmetry?
When we take the the Fourier Transform of a real function, for example a one-dimensional sound signal or a two-dimensional image we obtain a complex Fourier Transform. This Fourier Transform has special symmetry properties that are essential when calculating and/or manip- ulating Fourier Transforms.
