It is sometimes possible to use symmetry to find the Fourier coefficients, even though the criginal function is not symmetrical! With this thought in mind, consider the function in Fig Pl6.4. Observe that v(t) can be divided into the two functions illustrated in Figg P16.18(a) and (b). Furthermore, we can make v2(f) an even function by shifting it T / 8 units to the left. This is illustrated in Fig. P16.18(c). At this point we note that v(t)=v1(t) v2(t) and that the Fourier series of v1(t) is a

SOLVED: Find the amplitude spectrum (Fourier Transform) of a sinusoidal wave and a 20%, a 50% , a 100% duty cycle square pulse of amplitude (A) and frequency (F0) respectively. Explain what the fundamental and harmonic components are.
