Given the waveform in Fig. 15PFE-2, describe the type of symmetry and its impact on the trigonometric Fourier coefficient bn.

Figure 15PFE-2

a. bn = 0 for n even due to odd symmetry; bn is nonzero for n odd

b. bn is nonzero for all n

c. bn = 0 for all n due to half-wave symmetry

d. bn = 0 for n even due to half-wave symmetry; bn is nonzero for n odd
