Thread: Please help with the Fourier Series...

Hello, I am having difficulty with this Fourier Series:


6218_123.bmp
The 1st problem is stated as such; What is the amplitude of the second harmonic of V (Voltage).


The 2^nd problem is stated as such; What is the DC component of V (Voltage).


The 3^rd problem is stated as such; What is the Fundamental frequency of (Voltage).

It would be great if someone out there could help with all of part of this...

Best Regards

The 2nd harmonic of a Fourier series is defined as the component where . To find the amplitude of that component you take the derivative of for that fixed n and look at the extrema.

The DC component is found by evaluating at . Since the series begins at it would appear that the DC component is zero.

Wikipedia has a good article that explains what the fundamental frequency is: Fundamental frequency - Wikipedia, the free encyclopedia
