What property does the function hold which values equal the complex conjugate of the function with argument with opposite sign?$X(-\nu)=X^*(\nu)?$

Question

I know that if

$$X(-\omega) = X(\omega),$$

then the function $X$ is even.

Here I read that

In general, if a signal $x(t)$ is real, then $$X(-\omega) = X^*(\omega).$$

What is the name of this property of $X$?

Answer 1

Such a function is Hermitian.
