Section 14 Broadcast and Engineering

artificial satellite

• a human-made object placed into orbit around a celestial body like a planet

• a natural object that orbits a planet

• a spacecraft that travels between planets

• a device used to measure atmospheric conditions

broadcast

• to transmit a program or other information by radio or television

• to receive information from a satellite

• to record a program for later viewing

• to edit a video for online sharing

microwave dish

• a dish-shaped device that uses microwave transmissions to broadcast

• a type of cooking appliance that uses infrared radiation

• a satellite dish used for receiving television signals

• a container used for heating food in a conventional oven

signal

• the sound or image conveyed in telegraphy, telephony, radio, radar, or television

• a type of electronic device used for communication

• a method of encoding information for transmission

• a visual representation of data

viewing area

• A broadcast range that a broadcast station covers via radio waves

• The area where a station's signal is too weak to decode

• A term used for the physical location of a broadcast station

• The distance from which a viewer can see a television tower

fiber optics

• the use of thin, flexible fibers of glass or other transparent solids to transmit light signals

• a method of storing data on magnetic disks

• a technique for amplifying sound waves

• the process of converting electrical signals into light signals

geosynchronous orbit

• a special position high above the Earth that allows an object to keep pace with the rotation of our planet

• an orbit that is always directly above the North Pole

• a low Earth orbit that allows for quick satellite communication

• an orbit that changes position relative to the Earth's surface

transmitter

• A device that receives messages and signals

• A type of communication protocol

• Equipment used to transmit messages and signals

• A storage device for data

satellite dish

• a dish-shaped antenna that receives and transmits signals to and from a satellite in outer space

• a type of telescope used to observe distant stars

• a device for capturing radio waves from the atmosphere

• a large screen used for displaying satellite images

cable

• an assembly of electrical conductors insulated from each other but laid up together (as by being twisted around a central core)

• a type of software used for network management

• a device that converts electrical energy into mechanical energy

• a system for transmitting data over long distances
