Analog VS. Digital

Examples of Digital Technology

Three examples of digital technology are a CD, a digital clock, and a calculator. I know that these are all examples of digital technology because they each convert the signals they are given into a discrete amount of values differing in amplitude. These values are represented as zeros or ones, also known as binary code. (Common thread)

Examples of Analog Technology

Three examples of analog technology are a cassette tape player, an analog clock, and a microphone with speakers. I know these are all examples of digital technology because they each take the signals they recive and record it in its original form. Every value that is recorded represents an electrical pulse that varies from the others in amplitude. There is an unlimited amount of values in an analog signal. (Common thread)

3 Differences Between Analog and Digital Signals

One difference between analog and digital signals is that the analog signal is continuous, and the digital signal is discrete. A second difference is that analog signals vary in time, while digital signals change in individual steps. Lastly, a third difference is that an analog wave is the original wave, and a digital wave is sampled from the original wave.

3 Differences Between Analog and Digital Technology

One difference between analog and digital technology is that an analog signal is turned into an infinite amount of values varying in amplitude, and a digital signal is turned into binary code. Another difference is that analog technology can degrade over a long period of time, while digital technology does not degrade. A third and final difference between the two types of technology is that analog waves are denoted by sine waves, and digital waves are denoted by square waves.

Why Digital Technology is Preferred Over Analog Technology

One reason why digital technology is preferred over analog technology is that most people today are very familiar with digital technology. Most modern day kids are growing up in a digital world and know how to use and manipulate digital technologies/devices better than analog. Digital technology is simply a lot more popular than analog. A second reason why digital technology is preferred over analog technology is that analog technology is known to make some errors and is less accurate than digital technology, which is almost absolutely free from errors. A final reason why digital technology is preferred over analog technology is because analog technology will degrade after some time, but digital technology will not.
