Encontre o termo gen´ erico s ( k ) da soma dos k primeiros termos da progress˜ao do exerc´ ıcio 1, considerando r = 3 e r = 1. 3. Encontre a solu¸ c˜ao para a equa¸ c˜ao a diferen¸ ca de segunda ordem y ( k + 2) − y ( k + 1) − 2 y ( k ) = 5 . 2 k com y (0) = 3 e y (1) = 0, utilizando o M´ etodo dos Coeficientes a Determinar. 4. Calcule a Transformada Z das seguintes fun¸ c˜oes discretas (a) x ( kT ) = kT (b) x ( kT ) = sen ( θkT ) (c) x ( kT ) = e − akT cos ( θkT ) (d) x ( kT ) = 0 , 1 , 2 , 3 , , , , , ··· 5. Obter a transformada Z inversa para os seguintes casos, sendo T = 1: (a) X ( z ) = 1 , 6 z 2 − , 8 z 3 − 2 , 6 z 2 − 2 , 2 z − , 6 . (b) X ( z ) = , 6 z z 2 − 1 , 7 z +0 , 7 .
