Introduction To Analog And Digital
Up until recently, digital devices were the only widely available option, but advances in digital device technology have made mass production more affordable. Analog technology has the advantages of low cost and ease of use, but it cannot store as much information. Even though digital data is the only kind that computers can read, analog signals are easier to transfer. This has resulted in the widespread use of analog-to-digital and digital-to-analog converters. Indeed, most individuals are completely oblivious to the procedure as it unfolds before their eyes. When communicating with the outside world, a DSL modem like this one translates incoming and outgoing analog signals into digital ones before sending them to your network or computer.
If you were born between 1980 to 1999, you might know the value of owning a digital watch. Even in the early 2000s, the coolest thing you could own was a digital watch. None of us would have believed that a day would come when Analog watches would become rare and everyone would be using digital watches. Nowadays we see how Digital technology has replaced Analog technology, let’s see what the difference between the two is and which one is better.
What is Analog Technology?
Analog Technology is the signal derived from physical phenomena that may also be interpreted as signals that represent physical measurement. If you own an analog watch, the hands will move across a dial to indicate the time. The amount of motion the hands make indicates the time. The passage of twice quite so much time is indicated by the hour hand’s movement over two components of the dial as opposed to one. As clear as it may appear, there is a lot more nuance to it than meets the eye. The idea is that time is represented by the hand as it moves around the dial. It is not the same as time; rather, it serves as a metaphor for it. Just like when using a ruler to determine a value. A little piece of a wooden or plastic ruler is equal in length to your finger if you measure and mark its surface with the span of your finger. Of course, it’s not your actual finger; rather, it’s only a metaphorical depiction of one. That is the true meaning of the word “analog.”
Before computers took over the scientific and technological world in the early 20th century, almost all instruments for measuring physical quantities were analog. A moving-coil meter was used to measure electric current by having a little pointer move around a dial. As the needle climbed the dial, the current in the circuit increased. The pointer represented the flow of electricity. Weight scales, speedometers, decibel meters, and seismographs were all examples of equipment that operated similarly. The scope of analog technology, however, extends well beyond simple measuring instruments and mechanical pointers. Simply put, when we describe something as analog, we usually mean that it does not require digital processing of numbers in any way, shape, or form, either in the tasks it performs or the data it deals with.
Examples of analog devices are record players, cassette players, VCRs, etc. These devices linearly record information and read physical data from a media device by scanning it.
What is Digital Technology?
The word digital is derived from the Latin word ‘digitus’ meaning one of the oldest tools. Digital technology includes all automatic devices, electronic devices, resources that generate, process, or store information, and technological devices. In this technology, the information is converted into a binary system i.e. ‘0’ & ‘1’ where every bit is the symbol of two amplitudes.
With the help of digital technology, you can conveniently analyze and record the execution of your campaigns while marketing. It makes it simpler to record the campaigns that enable digital marketers to become accustomed to and determine improved results, which was less or not at all possible in analog marketing. There are some advantages of digital technology such as
- It reduces time and effort.
- It Reduces cost of services.
- It increases the speed of measurement.
- It provides instant feedback and result.
- It can reinforce learning.
Difference Between Analog And Digital
|Key Points||Analog Technology||Digital Technology|
|Signal||It is a continuous signal which represents a physical measurement.
|It is a discrete time signal generated by digital modulation.
|Waves||Analog is denoted by sine waves.
|Digital is denoted by square waves.
|Representation||This technology uses a continuous range of values to represent the information.
|This technology uses discontinuous or discrete values for the representation of information.
|Data Transmission||Analog technology is subjected to deterioration by noise during the transmission and read/write cycle.
|Digital technology can be noise-immune without deterioration during transmission and read/write cycle.
|Flexiblity||Analog instruments are not flexible.
|Digital instruments are flexible in implementation.
|Errors||Analog devices usually have scales that are cramped at the lower end and give observational errors.
|Digital devices are free from observational errors such as approximation errors and parallax.
|Examples||Analog electronic devices, human voice in the air, analog watches, and other analog devices.
|DVDs DVDs, Digital watches, and other electronic devices.
Analog or Digital , which one is better?
Today as digital technology takes over our lives, we are immensely drawn toward analog technology. Why is it so? The reason behind this is that even though digital technology has made our lives easier, it is not always accurate and one can not depend on it completely. We have a deep material, evolutionary and conceptual relationship with analog technology which is simply lacking in our connection with digital technology.
Though digital technology has its advantages, it has several drawbacks too. Let’s take an example of an analog watch, it is more accurate than the digital one. analog technology uses a wave that is recorded or used in its original form. Moreover, analog watches feature a very legible dial, wherein digital watches are more packed with indications everywhere.
