Advantages of Analog Signals

Here, are pros/benefits of Analog Signals

• Easier in processing
• Best suited for audio and video transmission.
• It has a low cost and is portable.
• It has a much higher density so that it can present more refined information.
• Not necessary to buy a new graphics board.
• Uses less bandwidth than digital sounds
• Provide more accurate representation of a sound
• It is the natural form of a sound.

Advantages of Digital Signals

Here, are pros/advantages of Digital Signals:

• Digital data can be easily compressed.
• Any information in the digital form can be encrypted.
• Equipment that uses digital signals is more common and less expensive.
• Digital signal makes running instruments free from observation errors like parallax and approximation errors.
• A lot of editing tools are available
• You can edit the sound without altering the original copy
• Easy to transmit the data over networks

Disadvantages of Analog Signals

Here are cons/drawback of Analog Signals:

• Analog tends to have a lower quality signal than digital.
• The cables are sensitive to external influences.
• The cost of the Analog wire is high and not easily portable.
• Low availability of models with digital interfaces.
• Recording analog sound on tape is quite expensive if the tape is damaged
• It offers limitations in editing
• Tape is becoming hard to find
• It is quite difficult to synchronize analog sound
• Quality is easily lost
• Data can become corrupted
• Plenty of recording devices and formats which can become confusing to store a digital signal
• Digital sounds can cut an analog sound wave which means that you can’t get a perfect reproduction of a sound
• Offers poor multi-user interfaces

Disadvantages of Digital Signals

• Sampling may cause loss of information.
• A/D and D/A demands mixed-signal hardware
• Processor speed is limited
• Develop quantization and round-off errors
• It requires greater bandwidth
• Systems and processing is more complex.
