Which one is mainly used for periodic signals?

A Fourier series is only defined for functions defined on an interval of finite length, including periodic signals, as you can see from the definition of the Fourier coefficients (in the basis einxn∈Z) an=12π∫π−πf(x)e−inx dx.

What is the area of periodic signal in a periodic interval?

9. What is the area of a periodic signal in a periodic interval? Explanation: The area of any periodic signal in any interval is the same. Hence it is same as the previous interval.

How are frequency components of a periodic signals related?

In such a case, the least common multiple of the two periods is the period of the sum signal. Alternatively, the fundamental frequency of each of the two periodic signals can be found and the greatest common factor of the two fundamental frequencies is then the fundamental frequency of the sum signal.
