How does Fourier series make it easier to represent periodic signals?

A)
Periodically related
B)
Harmonically related
C)
Sinusoidally related
D)
Exponentially related

Correct Answer : Option (B) :   Harmonically related

Explanation : Fourier series makes it easier to represent periodic signals as it is a mathematical tool that allows the representation of any periodic signals as the sum of harmonically related sinusoids.
