Question 1

Which of the following statements is true regarding FIR filters?

  • They include feedback.
  • They can have nonlinear phase.
  • They depend on past input samples only.

💡 Hint: Think about the definition of FIR.

Question 2

IIR filters are considered more efficient than FIR filters because:

  • They require more coefficients.
  • They include feedback.
  • They always maintain linear phase.

💡 Hint: Consider the implications of feedback.
