Question 1

Another way to signify an aspect ratio of 4:3 would be:

Accepted Answer

1.33:1

Answer

An aspect ratio of 4:3 means that for every 4 units of width, there are 3 units of height. To express this as a ratio to 1, you divide both numbers by the second number (3). Therefore, 4 divided by 3 is approximately 1.33, making the aspect ratio 1.33:1. This conversion is common for comparing different aspect ratios.

Question 2

What is a CCD in a video camera?

Accepted Answer

A light-sensitive electronic chip called a charge-coupled device

Answer

A CCD (Charge-Coupled Device) is a crucial component in many video cameras, acting as a light-sensitive electronic chip. It converts incoming light photons into electrical charges, which are then processed to form a digital image. The CCD array captures the visual information, making it fundamental to the camera's ability to record video.

Question 3

Composite video is made:

Accepted Answer

by combining the luminance and chroma information onto one cable

Answer

Composite video is an analog video signal format that combines all video information—luminance (brightness) and chrominance (color, or hue and saturation)—into a single signal. This combined signal is then transmitted over a single cable, which can lead to some signal degradation due to the intermingling of information. It was a common standard before the advent of separate component signals.

Question 4

Resistance is:

Accepted Answer

The opposition to the flow of electrons in Direct Current.

Answer

Resistance is a fundamental electrical property that quantifies the opposition a material or component presents to the flow of electric current. In a DC circuit, resistance directly impedes the movement of electrons, converting electrical energy into heat. It is measured in Ohms and is a key factor in determining current flow and voltage drop according to Ohm's Law.

Question 5

XLR connectors are:

Accepted Answer

Most commonly used with three conductors plus an outer shell that shields the connection and locks with mating connectors.

Answer

XLR connectors are widely recognized for their robust design, commonly featuring three pins for balanced audio signals, which helps reduce noise over long cable runs. The outer shell provides shielding against electromagnetic interference, and its locking mechanism ensures a secure and reliable connection, preventing accidental disconnections in professional AV environments.
