Solved Example 18 (i) Ω 0 = π/ 3, hence T = 6. s ( t ) is a linear combination of a constant and two rectangular pulse trains whose Fourier series coefficients are given by sin( kπ/ 3) and sin(2 kπ/ 3) The corresponding duty factors are 1 / 3 and 2 / 3. (ii) We have, for - 3 < t 3, x ( t ) = Z t - 3 s ( τ ) Thus x ( t ) is the area under the s ( · ) graph over the interval ( - 3 ,t ]. This function increases linearly (in t ) for - 3 t 2; remains constant for - 2 < t ≤ - 1; decreases linearly for - 1 < t 1; remains constant for 1 < t 2; increases linearly for 2 < t 3. (iii)
