(c) Even, odd, half-wave and quarter wave symmetry

(d) Half wave symmetry

This question was posed to me by my school principal while I was bunking the class.

Question is from Symmetry Properties of the Fourier Series topic in division Fourier Series of Signals and Systems

Answer 1

Right answer is (c) Even, odd, half-wave and quarter wave symmetry

The explanation is: The types of symmetry shown by signals are- Even, odd, half-wave and quarter wave symmetry.
