  1. Question 1 of 4
    1. Question

    The Daubechies wavelet with p=3 vanishing moments is universally optimal for all signals that are sampled fast enough to satisfy the sampling theorem.

    Correct
    Incorrect
  2. Question 2 of 4
    2. Question

    You wish to select a wavelet that will efficiently (many zero coefficients) represent a signal that consists of sections described by different polynomials. Which of the following are valid considerations for selecting a wavelet?

    Correct
    Incorrect
  3. Question 3 of 4
    3. Question
