φ (t) being the characteristic function of the distribution.
Corollary:
If φ (t) is absolutely integrable over R' i.e. if

Uniqueness theorem of Characteristics Function (cf):
Characteristics functions uniquely determines the distribution i.e. a necessary & sufficient condition for two distributions with p.d.f & f1 (.) and f2 (.) to be identical is that their characteristics functions
φ 1(t) and φ 2(t) are identical.
