# DIS Proposal

## Terms

Binary Code: digital code made up of 1s and 0s

Convert: Change

Continuous:On going and infinite.

## Analog and digital examples

Analog

• An analog clock because it can show the exact time without modifying it.
• The human voice because it is sound waves in their original form.
• An analog tape recorder because the signal is taken straight from the microphone and into the recorder without changing it.

Common thread: Always completely accurate and like the original.

Digital

• A digital clock because it only shows 1-9 and gives no indication of when it is going to change to the next number.
• A CD because a CD player reads the bumps and grooves on it and needs to convert it to binary code.
• DVDs because the DVD player has to read the bumps and grooves and change them into binary code so it can play the disk.

Common thread: Has to be modified or converted to be used.

## Differences in signals

Analog:

• Continuous
• Is still in its original form.
• Can have an outcome of any number.

Digital:

• Non-continuous
• Has been modified from the original.
• Binary code

## Differences in technology

Analog:

• Exactly as it is recorded.
• Uses continuous signals.
• Usually older.

Digital:

• While it is getting converted to binary code, sometimes it gets changed.
• Uses non-continuous signals.

## Which one?

Analog is usually more accurate than digital. This is because digital has to be converted into binary code and so there is a better chance that there could be a mistake.

Analog because it is faster. It is faster because there is less converting then digital so it will take less time.

Analog because sound waves are analog. If using analog, it will have good quality sound. If using digital, the sound quality would not be as good.

Overall, the DIS should switch to analog for their new game. They should switch because analog is more accurate, it has better quality, and it is faster.
