## Examples of Analog Technology

Analog Clock: An analog clock is one example of analog technology because an analog clock is an analogy for time. Also, since the clock keeps spinning and never stops, it has an infinite amount of values.

Cassette tape: A cassette tape is another example of analog technology because a cassette tape is an analogy for recorded audio. Also, because the tape recorder keeps spinning, like the analog clock, it has an infinite amount of values.

Seismograph: Finally, a seismograph is an example of analog technology because it is an analogy of earthquake waves. Also, because the ground is always in motion and the weight is always swinging back in forth, the seismograph has an infinite amount of values.

## Examples of Digital Technology

Digital Thermometer: One example of digital technology is a digital thermometer because it uses binary code. Also, because the numbers displayed can only go to a certain amount, there is a finite amount of values.

Digital Clock: Another example of digital technology is a digital clock because the numbers displayed also use binary code and there is a finite amount of values or solutions.

MP3 Players: Finally, MP3 players are an example of digital technology because they use binary code when storing and playing music. Also, the MP3 players have a finite amount of values.

## Differences Between Analog and Digital Signals

1. One difference between analog and digital signals is that analog signals are continuous, while digital signals are discrete (not continuous).

2. Another difference between analog and digital signals is that digital signals use the binary code (0's and 1's), while the analog signals use words, pictures and sounds.

3. The third difference between analog and digital signals is that analog signals can have many different amplitudes (smooth, continuous waves/sine waves, while digital signals can have only two different amplitudes (square waves).

## Differences Between Analog and Digital Technology

1. One difference between analog and digital technology is that analog technology stores the signals (words, pictures, and sounds), while digital technology converts the stored signals into numbers (digits).

2. Another difference between the technologies is that analog technology is a measurement/ representation of the signals, while digital technology displays the signals (in numbers/digits).

3. The last difference between digital and analog technology is that analog technology is recorded and used in its original form, while digital technology is sampled and, then converted into digits.

## Analog vs. Digital

I would prefer digital technology over analog because:

1. The first reason why I would choose digital technology over analog technology is because digital technology has a lot more durability. Analog technology has sound degradation because of the physical contact with the sensor where details on the electronic wear off, while digital doesn't degrade at all because the sensor on these does not make any contact to scratch it up.

2. The second reason why I would prefer digital technology is because there is a lot better sound quality from digital. Because of degradation, analog tends to sound more scratched up than digital. Also, when analog recordings are copied, they earn a lot of extra noise, called white noise. However, digital copies do add any additional noise.

3. The final reason why I think digital technology is better than analog is because digital has more portability. You can take digital sounds wherever on many different devices because it does not cause any extra white noise and it is very easy to transfer to other electronics. Analog devices are harder to carry around because they can easily be destroyed.
