Answer» Correct Answer - Option 1 : Analog ang Digital signal both
The correct answer is Analog and Digital signal both. - The form of Information Signal used in sending fax and email is Analog and Digital signal both
- Analog Signals
- These signals are continuous in both values and time.
- These were used in many systems to produce signals to carry information.
- These signals are more subjected to noise as they travel through the medium.
- Digital Signals
- These are not continuous, but signals are discrete in value and time.
- They can be noise-immune without deterioration during transmission.
- They are stored in the form of binary bits.
- When fax machines were introduced, they were all analogue devices. They transmitted the scanned lines as a continuous analogue signal through the phone line.
- Traditional analogue fax uses a phone line that can send or receive only one fax at a time, and only in one location.
- However, sending an e-mail is a pure digital signal.
