The waveform is given by V(t) = 10 sin (2π 100t). What will be the magnitude of the second harmonics in its Fourier series representation

ক

0 V

খ

20 V

The Fourier series coefficient of signal x(t) is CK, then what will be Fourier series coefficient of the signal, x(0.5t) + x(t – 0.5) + x(-2t)?

ক

C<sub>K </sub>(1 + e<sup>-jω0.5k</sup>) + C<sub>-K</sub>

খ

C<sub>K </sub>(2 + e<sup>-jω0.5k</sup>) + 0.5 C<sub>-K</sub>
