Questions and Answers

Which equation correctly represents the signal y(n) in terms of x(n) and delta(n-k)?

  • y(n) = delta(k-n)
  • y(n) = delta(n-k)
  • y(n) = x(k-n)
  • y(n) = x(n-k) (correct)

    • What is the relationship between the variables n and k in the equation y(n) = x(n) * delta(n-k)?

  • There is no relationship between n and k
  • n and k are inversely proportional
  • n and k are equal
  • n and k are directly proportional (correct)

    • What does the symbol delta(n-k) represent in the equation y(n) = x(n) * delta(n-k)?

  • The ratio of n and k
  • The difference between n and k (correct)
  • The product of n and k
  • The sum of n and k

    • If x(n) = 0, what is the value of y(n) in the equation y(n) = x(n) * delta(n-k)?
