Discrete - Time System Identification You are given a causal discrete-time linear time - invartiant (LTI) system with unkown impulse response h[n] to analyze. When the five-sample causal signal x[n] given below is input into the unkown system, the response y[n] is six samples long and causal, as shown below. x[n] 4 2 123456 x-[1234500]; y=[11111-50]; y[n] 4 2 n 5 n 12 2 3 4 6 -2 -4

Affempt all Questions. A discrete-time signal x(n) is defined as x(n) = 0sns4 elsewhere (a) Determine its values and sketch the signal x(n). (b) Sketch the signals that result if we: (1) First fold x(n) and then delay the resulting signal by three samples. (2) First delay x(n) by three samples and then fold the resulting signal. A BI !!
