Question 1

Any light-emitting system such as a television monitor is subtractive, conversely, solid objects, including print media do not emit light and are perceived through an additive process.

Accepted Answer

Any light-emitting system such as a television monitor is additive, while solid objects, including print media, are perceived through a subtractive process.

Question 2

The definition of a primary color is that it cannot be created through a combination of any of the other primary colors.

Accepted Answer

This is the basic principle of the color theory and is widely accepted. The three primary colors are red, blue and yellow. Secondary colors, green, orange and purple are created by mixing two primary colors together. Tertiary colors are created by mixing a primary color with a secondary color.

Question 3

Vertical octaves are frequencies that change by adding the initial frequency or fundamental to itself again rather than doubling the frequency.

Accepted Answer

Vertical octaves are also known as harmonic overtones and are found in the harmonic series. They occur when the frequency is multiplied by any integer multiple of the fundamental frequency. Doubling the frequency results in the next higher octave, which is a horizontal octave.

Question 4

Saturation is the ratio between how much color and how much light there is in the signal.

Accepted Answer

Saturation refers to the intensity or purity of a color, indicating how much it is free from the influence of white light. It does not directly involve the ratio between color and light in the signal.

Question 5

The designation of R-Y and B-Y were later changed to Pr and Pb for analog signals.

Accepted Answer

R-Y and B-Y were designated as Pr and Pb in the early 1990s to conform to International Telecommunication Union (ITU) standards for analog signals.

Question 6

Which of the following is not a secondary color?&#10;A) cyan&#10;B) yellow&#10;C) green&#10;D) magenta

Accepted Answer

Green is a primary color in the additive color model (RGB), while cyan, yellow, and magenta are secondary colors in the subtractive color model (CMY).

Question 7

The addition of color to the video signal slowed down the frame rate to frames per second (fps).&#10;A) 24&#10;B) 25&#10;C) 29.97&#10;D) 30

Accepted Answer

The addition of color to the video signal resulted in the implementation of the NTSC standard, which set the frame rate to 29.97 fps in North America.

Question 8

The is a reference point for the color signal that consists of 8-11 cycles of the subcarrier during the back porch of the horizontal blanking period.&#10;A) phase shift&#10;B) color burst&#10;C) black balance&#10;D) white clip

Accepted Answer

The description fits the definition of a color burst, which is a reference point for the color signal that consists of 8-11 cycles of the subcarrier during the back porch of the horizontal blanking period. A) Phase shift refers to a change in phase of a signal. C) Black balance is a calibration process to ensure that black levels are consistent across a video signal. D) White clip refers to the point at which white levels in a signal are clipped or cut off.

Question 9

The color information minus the luminance information is known as the&#10;A) 3.58 color reference&#10;B) color difference signal&#10;C) I and Q Vectors&#10;D) both A and B

Accepted Answer

The color information minus the luminance information is known as the color difference signal. None of the other options match this definition.

Question 10

Which of the three systems described in the text achieves the best color?&#10;A) NTSC&#10;B) PAL&#10;C) SECAM&#10;D) none of the above
