2 Answers2 In all the terms in the dots, the power of h is greater than 2, so you can factorize by h 2 Moreover ( n 1) = n ( x h) n = ( x h) ( x h) ⋯ ( x h) To expand the RHS, we must pick either x or h from each bracket, and multiply them together to produce a term The full expansion consists of the sum of the terms produced6 l y(n) You are told that h1(n)=u(n)2u(n1)u(n2) You observe that the step response of the total system is s(n)=2r(n)3r(n1)r(n2) where r(n)=nu(n) Find and sketch h2(n) 1218 The impulse response of a discretetime LTI system is given by h(n)= ⇢ 1ifn is a positive prime number 0 otherwise (a) Is the system causal?24 c JFessler,May27,04,1310(studentversion) 212 Classication of discretetime signals The energy of a discretetime signal is dened as Ex 4= X1 n=1 jxnj2 The average power of a signal is dened as Px 4= lim N!1 1 2N 1 XN n= N jxnj2 If E is nite (E < 1) then xn is called an energy signal and P = 0 If E is innite, then P can be either nite or innite
