What are Analog Signals?
There are different forms of signals one of them is the analog signal. It is defined as the type of signal that are used to express the quantities that are based on the variability of time and different type of time based processes such as electrical, some of mechanical and hydraulic etc are called as the analog signals. Different type of minute fluctuations are used fro the sake of process by analog signals. They also use the same method to pass on the information between different places. Wires are used for the processes of analog signals.
What are Digital Signals?
Digital signals are quite different from the analog signals because they are based on the numeric methods. It is defined as the types of signal which are used to represent the quantities which use the numeric method to deliver the information are called as the digital signals. Basically they are in discrete form. Some times they are said to be more reliable in the field of computer technology because they are used to transfer data. With the presence of continuous waves in the digital signals they really helpful in avoiding the rise an fall like in analog signals.
Difference between Analog and Digital Signals:
If we discuss the different between these two forms of the signals that is; analog and digital then we should discuss it in different aspects such as working, their architectures, pros and cons as well. The major differences among the two signals are listed below
Difference in Working:
The working of analog and the digital signals are very much different from each other in their processes respectively. If we compare the working of the digital signals with the analog signals then the working of the digital signals are more reliable and accurate because they use the digital media or the numeric method where as analog signals are based on the small fluctuations. For the sake of the passing the information from one medium to another analog uses some part of it. One of the primary difference between the analog and the digital signal is that digital signals are used to play that information which is came from re-sampling, whereas analog are known for playing recorded data. Digital signals have priority over analog signals because with the help of digital signals users have ability to change the visual and the audio or re-record it but with analog signals you can do such parameters. So generally analog signals are used record the sound waves such as cassettes fro tape recorders etc, and they also have ability to record the data in its original from. But digital signals are not able to record the data in the original form but they can do the sampling only and record it.
Pros and Cons of Analog Signals:
Some of the important advantages and disadvantages are listed below of analogous signals.
- One of the major advantages of the analog signal is that they have power to define infinite amount of data.
- Density of the analog signals is much higher as compared to digital ones.
- Analog signals have easy processing.
- Unwanted noise in recording.
- If we transmit data at long distance then unwanted disturbance is there.
- Generation loss is also a big con of analog signals.
Pros and Cons of Digital Signals:
Digital signals also have some advantages and disadvantages like analog signals
- Because of their digital nature they can travel faster in over digital lines.
- Ability to transfer more data as compared to analog.
- Greater bandwidth is essential.
- Systems and processing is more complex.
