The gray plot and red plot attempt to transmit the same signal in the graph below. What is the best conclusion that can be drawn?

• The gray plot is a discrete analog signal.

• The red plot is a discrete digital signal.

• The red plot is a discrete analog signal.

• The red plot cannot transmit a useful signal because of its box like shape.

The drawing shows two waves. Which statement best compares these two waves?

• Wave 1 has a higher frequency because it has a longer wavelength than wave 2.

• Wave 1 has a higher frequency because it has a higher amplitude than wave 2.

• Wave 2 has more energy because it has a higher amplitude than wave 1.

• Wave 2 has more energy because it has a higher frequency than wave 1.
