What are the advantages of analog modulation over digital modulation?

Answer 1

1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation

Answer 2

Digital instruments can work with discrete information and manipulate it to yield any logical results. Analog instruments cannot manipulate information in a logical form, but can only do other analog forms (ie: any instrument with a needle, such as pressure gauges, (older) volt meters). Manipulating information in a logical way can yield to a much larger, and generally more useful results, like your computer.

Answer 3

There are many applications where analog instruments are preferred. Example: in earthquake charting, a slow-moving needle detecting disturbances runs for months unatttended. It could be done with digital data and digital instruments but storing many months of data becomes a chore. And to find results is easier on a chart than having to process the data and finally getting a hard copy, while using analogue the results are immediatel visible,not to mention cheaper.

Advantages and Disadvantages of the Digital Instruments

These days there is greater trend of using the digital instruments for measurement of all the important quantities like weight, length, temperature, humidity, current, voltage, rpm and even the blood sugar level. There are also digital instruments for measurement of the blood pressure, heart beat rate, and others.

Here are some of the advantages of the digital instruments over the analogue instruments:

1) They are very easy to read.

2) Since there are very few moving parts in the electronic instruments, they are usually more accurate than the analogue instruments. Even the human error involved in reading these instruments is very less, which adds to the accuracy of digital instruments.

3) The electronic items tend to be cheaper than the mechanical items.

4) The data from the instruments can be recorded for future reference.

5) The output of the digital devices can be obtained in the computer

There are also some disadvantages of the digital instruments. Here they are:

1) Sometimes they tend to indicate erratic values due to faulty electronic circuit or damaged display.

2) In case of high humidity and corrosive atmosphere the internal parts may get damaged and indicate the faulty values.

3) Sometimes these instrument show some readings even though there is no applied measurable parameter.

On the whole, the advantages of the digital instruments outdo the disadvantages, which is why they have become highly popular. You can find digital instruments in the cars, air planes, motor cycles, and also in places like air ports, railway stations, public places etc. The digital clocks are one of the most widely used instruments for the personal use and also in public and private places. The trend is towards the digital instruments since they are convenient to use and also have excellent looks. In future their use is sure to increase much more.
