# Analog and Digital

## Analog examples

3 analog ex:

1. Mega phone
2. Stereo system
3. Guitar

Analog- they have physical information and do not have codes (1,0,1,0,1,0,1,1)

## Digital examples

3 digital ex:

1. Mobile phone
2. Computer
3. Digital clock

Digital- I know because they don't have physical data on them and they have codes (1,0,1,0,1,0,1,1)

## 3 differences between analog and digital signals

1. Analog is a wave of electric currents. Digital is a wave of electric pulses that represent digits of binary.
2. Analog doesn't have codes and digital does... (0,1,0,1,0,1,1) binary code!
3. Analog is similar in frequency and amplitude. Digital is similar to 1 and 0 pulses, every pulse is 1 and every missing pulse is 0.

## 3 differences between analog and digital technology

1. Analog signals go through a telephone, the sound in the transmitter travels to the receiver on the other side and when the other person talks it goes through the transmitter and travels through the wires to the receiver again. Digital signals go through a CD which is an aluminium layer with pits in the CD that create the sound.
2. Digital signals travel through CD players too and the CD player reflects light from the surface of the CD itself. Analog signals travel through record players, the vibrating of the electromagnet creates and electric current that is used to produce sound.
3. Analog- in vinyl records, the analog signal is carved into a grooved plastic disk, the sound is represented by the grooves in the disk.
Digital- the amplitude of the sound wave is sampled many times per second, each wave represents a digital sample of a sound wave

## My opinion

In my opinion I would want to play the Digital game. I think that the Digital game would be best because the quality would be very good, information is the same every time it is read, so there is no loss in quality over time. There is many uses for digital, for example a computer makes millions of decisions every second and its better to make the decision
when the value is small so it doesn't have to take in a lot of info and it can just separate the big pieces of information and use binary code (1,0,1,0,1,1,0,0,1,0,1).
i think it would appeal to the consumer because it would run smoothly and not lose the data that is left on the game. I don't think the cost is a big deal because there is no point in buying a bad game if it has a bad quality and isn't going to appeal to the consumer. But there is a point to buying a game thats a little more expensive and has good quality and the consumer will take some interest in it.
