Communication Systems

Task

Communication Technology comes in many forms and is ever changing in our world.  Messages, ideas, and images can be shared through television, radio, wireless devices, printed paper, the internet and through other digital media.  Despite their different forms, all methods of communication have a similar way of working and six key components:

1. Source

2.Encoder

The Medium/Channel - which consists of the following:

      3.Receiver

      4.Transmitter

5.Decoder

6.Destination

                               

PLEASE REVIEW THE TASK!

What do I do?

Your task is to answer questions #1-3 on the ANSWER SHEET located in your challenge packet. Answer all questions completely and with detail/evidence from the website link given.

For question #4 (i Movie Trailer) you must complete the planning template BEFORE filming. This will help organize the different components of the message you wish to convey.

  1. Use the link below to explore how human Communication Technology has evolved over time. Compare and contrast the strengths and weakness of four of the methods listed. Be sure that your examples come from VERY DIFFERENT time periods!

2. Review the Communication Components and diagram below, then answer the question.

Source: Starting point/Origin of a message

Encoder: Changes a message into other forms/signals for transmission

Medium/Channel: Means by which a message reaches its target

Receiver: Accepts the encoded information

Transmitter: Sends the message to the decoder

Decoder: Translates the encoded message/signals into understandable form

Destination: Where the message goes

 

Examples:                                           

                      

 

 

 

 

 

 

 

A communication link between a Coast Guard patrol boat and its base station is shown below.

The boat uses the satellite to communicate its position to the base station.

a. Explain the purpose of a decoder in a communication system.

b. Identify one of the decoders in this system and describe how it is used.

c. Explain the purpose of a transmitter in a communication system.

d. Identify one of the transmitters in this system and describe how it is used.

e. On the diagram, label the: source, encoder, receiver, transmitter, decoder and destination

 

 

  1. Your final task is to use your iPad to design an iMovie Trailer that uniquely/clearly displays and labels/Identifies all the components of a communication system.
