d. even-ordered harmonics

e. odd-ordered harmonics

Expert Solution

To determine

(a)

Whether dc term, cosine terms, sine terms, even ordered harmonics and odd ordered harmonics will be present in the given Fourier Series representation or not.

Answer to Problem 1P

The D.C. term is not present in the waveform, cosine terms are not present in the waveform, sine terms are present in the waveform, even ordered harmonics are not present in the waveform and odd ordered harmonics are present in the waveform.

Explanation of Solution

Calculation:

The waveform for Fourier series representation is drawn as shown in Figure 1.

Introductory Circuit Analysis; Laboratory Manual For Introductory Circuit Analysis Format: Kit/package/shrinkwrap, Chapter 26, Problem 1P , additional homework tip 1

Case 1:

D.C. value is the average value of the waveform. And as the area above the horizontal axis and below the horizontal axis is equal, so the value of area and the average is zero for the waveform.

Therefore, D.C. term is not present in the waveform.

Case 2:

If waveform is symmetric about vertical axis, it has an even symmetry. And for an even symmetry, the wave Fourier series contains D.C. and cosine term.

As waveform is not symmetric about the vertical axis, it means cosine terms are not present in the waveform.

Case 3:

If waveform is symmetric about origin it has odd symmetry. And for odd symmetry wave Fourier series contain D.C. and sine term.

As waveform is symmetric about origin, it means sine terms are present in the waveform.

Case 4:

Cosine term is even function and sine terms are odd function.

As waveform does not contain cosine term, therefore, even ordered harmonics are not present in the waveform.

Case 5:

Conclusion:

Thus, D.C. term is not present in the waveform, cosine terms are not present in the waveform, sine terms are present in the waveform, even ordered harmonics are not present in the waveform and odd ordered harmonics are present in the waveform.
