    1. Question

    Why is an analog low pass filter normally used prior to sampling a signal? Select all that apply.

    Correct
    Incorrect
  2. Question 2 of 2
    2. Question

    2. You are interested in the frequency range |f| < 500 Hz and have an analog anti-aliasing filter with stop band |f| > 750 Hz. Identify the sampling frequencies that will prevent noise in the 500 < |f| < 750 Hz range from aliasing into the band |f| < 500 Hz. Select all that apply.
