  1. Question 1 of 4
    1. Question

    A signal x[n] = \cos(\pi n/4)0.8^n u[n] is applied to an LTI system and produces an output 3u[n]. What output is produced by an input z[n] = 2x[n-3]?

    Correct
    Incorrect
  2. Question 2 of 4
    2. Question

    An LTI system has impulse response h[n] = 0.5^nu[n]. What input x[n] will produce an output y[n] = 3(0.5)^{(n-1)}u[n-1]?

    Correct
    Incorrect
  3. Question 3 of 4
    3. Question

    An LTI system with impulse response h[n] = u[n] is BIBO stable.

    Correct
    Incorrect
  4. Question 4 of 4
    4. Question

    LTI systems 1, 2, and 3 have impulse responses h_1[n], h_2[n] and h_3[n], respectively and are interconnected as follows. The input x[n] is first applied to system 1, then the output of system 1 is applied to systems 2 and 3 arranged in parallel, and the outputs of systems 2 and 3 are summed to produce the output y[n]. We seek an expression for the impulse response h[n] of the overall system relating x[n] to y[n]. Select all correct answers.
