    AC stands for

    Explanation
    AC stands for Alternating Current. Alternating current is an electric current that periodically reverses direction. It is commonly used to transmit electrical energy for power distribution. Unlike direct current (DC), which flows in only one direction, AC changes direction at regular intervals, typically 50 or 60 times per second. This allows for efficient transmission over long distances and easy voltage transformation using transformers. AC is the most common form of electrical power used in homes, businesses, and industries worldwide.

    What does a prism block do?

    • Reflects light into the camera

    • Splits the light entering the lens into 3 primary colours so it can be captured by an image sensor

    • Creates HD video

    • Blocks the prisms

    Correct Answer
    A. Splits the light entering the lens into 3 primary colours so it can be captured by an image sensor
    Explanation
    A prism block splits the light entering the lens into 3 primary colors so it can be captured by an image sensor. This is important because the image sensor in a camera can only detect and process light in these primary colors. By splitting the light, the prism block allows the camera to capture a full-color image that accurately represents the scene being photographed.

    The aspect ratio for the ATSC HD video is

    • 16x9

    • 4x3

    • 8x11

    • 5x1

    Correct Answer
    A. 16x9
    Explanation
    The correct answer is 16x9. This aspect ratio is commonly used for widescreen displays and is the standard for high-definition television (HDTV) broadcasts. The first number represents the width of the screen, while the second number represents the height. In this case, the width is 16 units and the height is 9 units, resulting in a wide rectangular shape that is ideal for displaying content in a cinematic format.

    How is timecode represented?

    • M:H:S:R

    • H:M:S:F

    • S:H:M:F

    • A:B:C:D

    Correct Answer
    A. H:M:S:F
    Explanation
    Timecode is represented in the format of H:M:S:F, where H represents hours, M represents minutes, S represents seconds, and F represents frames. This format is commonly used in audio and video production to precisely identify and synchronize specific points in time. The use of hours, minutes, seconds, and frames allows for more accurate and detailed time measurements, ensuring precise editing and synchronization of media content.

    DBU is measured at 

    • -6 dBFS

    • 0 VU

    • +4 dBU

    • 66

    Correct Answer
    A. +4 dBU
    Explanation
    dBU is a unit of measurement used to quantify the audio signal level in decibels relative to a reference level of 0 dBu, which corresponds to 0.775 volts. The correct answer, +4 dBU, indicates that the audio signal is measured at a level 4 decibels above the reference level. This means that the signal is relatively high in amplitude, indicating a strong audio signal.

    Drop frame timecode

    • Skips the first 2 frames every minute

    • Doesn't skip on the 10's

    • Uses ;

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The given correct answer, "All of the above," suggests that drop frame timecode skips the first 2 frames every minute, doesn't skip on the 10's, and uses a semicolon (;). This means that all three statements mentioned in the question are true for drop frame timecode.

    Name 3 ATSC video formats.

    • 900

    • 1080I

    • 720p

    • 3200

    • 4k

    • 1

    Correct Answer(s)
    A. 1080I
    A. 720p
    A. 4k
    Explanation
    The question asks for three ATSC video formats. The answer lists three formats: 1080I, 720p, and 4k. These formats refer to different resolutions for video display. 1080I represents interlaced video with a resolution of 1920x1080 pixels, 720p represents progressive scan video with a resolution of 1280x720 pixels, and 4k represents ultra-high-definition video with a resolution of 3840x2160 pixels.

    • 700 Mv

    • 100 IRE

    • 7.5 Mv

    • 0 IRE

    Correct Answer
    A. 700 Mv
    Explanation
    The maximum white level for a Digital waveform monitor is 700 Mv. This is the highest level of voltage that can be displayed on the monitor, indicating the brightest white color that can be reproduced.

    Humans can hear up to

    • 20 Herts

    • 20 kHerts

    • 30, 000 Herts

    • 200 kHerts

    Correct Answer
    A. 20 kHerts
    Explanation
    The human hearing range typically extends from 20 Hertz to 20,000 Hertz. This means that humans can hear sounds with frequencies as low as 20 Hertz and as high as 20,000 Hertz. The correct answer, 20 kHertz, represents the upper limit of the human hearing range.

    Interlaced scans line 1, line 2, line 3, etc.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Interlaced scans do not occur in a sequential order of line 1, line 2, line 3, etc. Instead, interlacing involves displaying even-numbered lines first, followed by odd-numbered lines, resulting in a flickering effect. Therefore, the correct answer is false.

    • 29.97

    • 60

    • 300

    Correct Answer
    A. 29.97
    Explanation
    The correct answer is 29.97. This is the standard frame rate for color television in most countries. It is slightly lower than 30 frames per second to accommodate for the color encoding process. The 29.97 frame rate ensures smooth motion and accurate color reproduction on television screens.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Modulation is making a change to a carrier frequency to add video, audio, data. Frequencies like AM and FM. Encoding is eliminating or removing redundant data to fit bandwidth limitations.

    Explanation
    Volume units (Vu) are measured at the 0 Vu level. This is the reference level for measuring audio volume. The other options mentioned in the question, such as 4+ dBU and -3 dBFS, are different measurement scales used in audio engineering but they are not specifically related to the measurement of volume units.

    Balanced audio has 3 wires. What are they called?

    • Red, blue, green

    • Balanced, unbalanced, balanced

    • Signal, Signal, Ground

    • Cable, XLR, RGA

    Correct Answer
    A. Signal, Signal, Ground
    Explanation
    Balanced audio requires three wires: two for carrying the signal and one for grounding. The two signal wires carry the audio signal in opposite phases, which helps in canceling out any external interference. The ground wire is responsible for providing a reference point for the audio signal. Therefore, the correct answer is "Signal, Signal, Ground."

    What is the most important part when building a mix?

    • Equalizer

    • Input Gain

    • Microphones

    • Nothing

    Correct Answer
    A. Input Gain
    Explanation
    The input gain is the most important part when building a mix because it controls the level of the audio signal entering the mixer. Properly setting the input gain ensures that the audio signal is neither too low nor too high, preventing distortion or loss of detail in the mix. It is crucial to achieve a balanced and clean sound before applying any further processing or adjustments in the mixing process.

    What 3 are the correct sampling rates?

    • 4:4:4

    • 4:2:0

    • 4:3:0

    • 4:2:2

    • 2:3:4

    • 4:4:1

    Correct Answer(s)
    A. 4:4:4
    A. 4:2:0
    A. 4:2:2
    Explanation
    The correct sampling rates are 4:4:4, 4:2:0, and 4:2:2. These numbers represent the chroma subsampling ratios used in video compression. The first number represents the sampling rate for the luminance (Y) component, while the second and third numbers represent the sampling rates for the chrominance (Cb and Cr) components respectively. 4:4:4 means that all three components are sampled at the same rate, resulting in no loss of color information. 4:2:0 means that the chrominance components are sampled at half the rate of the luminance component, leading to some loss in color detail. 4:2:2 means that the chrominance components are sampled at a higher rate than 4:2:0, resulting in better color representation than 4:2:0 but still less than 4:4:4.
