Sending Binary Messages

Develop your Protocol: Develop a protocol that allows you to use Internet Stimulator to relay a 2-bit message, i.e. one member sends a message and the other member sends the same message back. You or a teacher will say "Go" to begin the exchange, but otherwise all communication must be through the widget. As you're working consider.

• How will you know when the exchange is supposed to begin?

         You will know when the exchange is suppose to begin once one member has finished the message. Then, the other member can send the same message back.

• How will you know whose turn it is to send or receive the message?

        You will know whose turn it is to send or receive the message by setting a protocol between you and your member. You two must decide on the timing protocol and how many times you are going to the send the message. For instance, the members decide to send the message ABAB four times at a rate of 4 secs each letter, then once the other member receives the message ABAB four times as planned, then they can begin to send the same message back. 

• How will you coordinate your actions?

       You will coordinate your actions by setting a timing protocol which will allow messages to be sent at a constant time. 

Your Protocol: List the steps/ rules of your protocol.

1. Since we did not have a time protocol neither my partner or I was able to receive the message we intended to send each other. We sent each letter at a different time rate, a rate that was very inconsistent. Therefore, we had to set some rules. 
2. My partner Sebastian and I decided to use 3 secs as our time protocol. We would wait 3 seconds until we could send each letter. 
3.  We decided to use ABBA as our message and send it 3 times. 
4.  I was the first one to go and then once I finished sending the message ABBA four times, each letter sent after 3 seconds, then it was Sebastian's turn.   

Respond:

1. A binary message consisting of 4 bits was sent to you by a friend. The message was supposed to be ABAB. Unfortunately, your friend sent the message at one-half the but rate you agreed upon, while you read the message at the original rate. What message did you receive instead?   - The message I received instead was AABB.
2. A binary message was recorded as a wave, as shown in the image below. Can you decode the message? Explain what information you would need in order to successfully decode the message into A's and B's.                                                                                                                  -You can decode the message. In order to successfully decode the message into A's and B's, there must be a constant time. At a constant time you must send one A and then a B. To get a constant AB pattern it must be sent at a constant time.
