Fourier Series Analise da Onda Triangular Usando Diferenciação

59 Consider the triangular wave xt shown in Fig 513a Using the differentiation technique find a the complex exponential Fourier series of xt and b the trigonometric Fourier series of xt The derivative xt of the triangular wave xt is a square wave as shown in Fig 513b a Let xt sum from k to of ck ejkω₀t ω₀ 2πT₀ 5118 Differentiating Eq 5118 we obtain xt sum from k to of jkω₀ ck ejkω₀ t 5119 Fig 513
