    問題一覧

  • 1

    is exchanging any type of message between a sender and receiver.

    Communication

  • 2

    refers to communication that uses a transmitter, communication channel, and receiver. The message is called information, or an intelligence signal, in the form of an electronic signal.

    Communication systems

  • 3

    The first step in sending a message is to convert it into an electronic form suitable for transmission.

    Transmitter

  • 4

    It is the medium wherein an electronic signal is sent from one point to another.

    Communication Channel

  • 5

    a material that conducts electricity and allows the flow of charge such metals and metal alloys. The channel can be as simple as a pair of wires that carry a voice signal from a microphone to a headset.

    Electrical conductor

  • 6

    can be a fiber-optic cable or light pipe that carries the message on a light wave. These are used today to carry long-distance calls and all Internet communications.

    Optical media

  • 7

    The resulting system is known as radio when free space is the channel. Radio is the term applied to any wireless communication from point to point.

    Free space

  • 8

    Other communication channels are used in special communication systems such as sonar; water is used as the medium. L

    Others

  • 9

    It is a set of electronic components and circuits that accept transmitted messages from the channel and translate them back, which humans understand.

    Receiver

  • 10

    produce an increased version of the input signal.

    Amplifiers

  • 11

    produce a continuous, repeated, and alternating waveform without input.

    Oscillators

  • 12

    combine two or more electronic signals into one or two output signals.

    Mixers

  • 13

    combine two or more electronic signals into one or two output signals.

    Turned circuits

  • 14

    a circuit capable of amplifying specific frequencies while attenuating others.

    Filters

  • 15

    This diagram consists of five (5) blocks that represent elements used in the system that go in what order?

    Information Source, Transmitter, Channel, Receiver, and Destination.

  • 16

    Heinrich Hertz discovered _____ on _____?

    Radio waves, 1887

  • 17

    Samuel Morse discovered _____ on _____?

    Telegraph, 1837

  • 18

    The development and the first use of the Internet was done by whom and when?

    Tim Burners-Lee, 1982-1990

  • 19

    The telephone was invented by whom and when?

    Alexander Graham Bell, 1876

  • 20

    One-way or ____________ is considered the simplest way electronic communication is conducted.

    Simplex communication

  • 21

    A ________ can be a full duplex or a half-duplex.

    Duplex communication

  • 22

    communication is two-way, wherein people communicating can talk and listen simultaneously with devices that can send and receive signals simultaneously. Ex. Telephone

    Full Duplex

  • 23

    communication is still a two-way communication, but the direction alternates, and the communicating parties take turns transmitting and receiving. Most military, fire, aircraft, and marine radio transmissions, and walkie talkies.

    Half Duplex

  • 24

    It is a continuously varying voltage or current.

    Analog Signal

  • 25

    Digital signals do not change continuously but vary in discrete increments compared to analog signals.

    Digital Signal

  • 26

    is a single-frequency analog signal.

    Sine Wave

  • 27

    It uses Morse code, a system for short (dots) and long (dashes) signals to represent letters and numbers.

    Telegraph

  • 28

    Also known as radio telegraphy, a sine wave signal is turned off and on for short or long durations to represent the dots and dashes.

    Continuos wave code

  • 29

    represent numbers, letters, or special symbols in computers transferred serially through a wire, radio, or optical medium.

    Binary codes

  • 30

    ASCII stands for...?

    American Standard Code for Information Interchange

  • 31

    it is an electromagnetic or electrical current representing the information or data it carries from the source it was produced to its destination;

    Signal

  • 32

    It means amplification in a manner that if a signal is applied to a circuit, and its output has a greater amplitude than the input signal, then the circuit has gain

    Gain

  • 33

    It is the loss fed by a circuit or component.

    Attenuation

  • 34

    The message is called _____ or an intelligence signal, in the form of an electronic signal.

    Information

  • 35

    Some electronic circuits, called ______, reduce the amplitude of a signal rather than increase it

    stages

  • 36

    The gain or attenuation of a circuit is expressed in __________ which is a unit of measurement to express the hearing response of the human ear to sound levels. It is one-tenth of a bel.

    Decibels

  • 37

    The frequency of electromagnetic waves is measured in cycles per second (cps) or ______

    Hertz
