When does a wave posses a quarter wave symmetry?
(a) It has either even or odd symmetry
(b) It has half wave symmetry
(c) even/odd symmetry and half wave symmetry
(d) It is even in one quarter and odd in the other
This question was addressed to me by my school teacher while I was bunking the class.
My question is based upon Symmetry Properties of the Fourier Series in chapter Fourier Series of Signals and Systems
