### Symmetrical and Anti symmetrical signal

Symmetrical signal or even signal :

A signal x (t) is said to be symmetrical or even if it satisfies the following condition.

Condition for symmetry : x(t) = x(-t)

Where,  x(t) = Value of the signal for positive "t" and x(-t) = Value of the signal for negative "t".

An example of symmetrical signal is a cosine wave shown in figure : This article also gives the some properties of even and odd signals

Anti symmetrical signal or odd signal :

A signal x(t) is said to be Anti symmetrical or odd if it satisfies the following condition,

Condition for anti-symmetry : x (t) = -x(-t)

An example of odd signal is a sine wave shown in figure :

Symmetrical signal or even signal :

A signal x (t) is said to be symmetrical or even if it satisfies the following condition.

Condition for symmetry : x(t) = x(-t)

Where,  x(t) = Value of the signal for positive "t" and x(-t) = Value of the signal for negative "t".

Anti symmetrical signal or odd signal :

A signal x(t) is said to be Anti symmetrical or odd if it satisfies the following condition,
