Which of the following is used for modulation and demodulation?
Which of the following is used for modulation and demodulation?
The correct option is A Modem
Modem is used for
modulation and demodulation
Modems are intended to
convert digital signals to analog and vice versa. ... The modem converts the
analog signal on the phone line into a digital signal into the computer.
Modulation is the process of converting an analog signal into a digital signal,
and demodulation converts it back to analog.
Difference between Modulation
and Demodulation. Modulation is the process of influencing data information on
the carrier, while demodulation is the recovery of original information at the
distant end from the carrier. Modem is the equipment that performs both
modulation and demodulation.
A modem is a device or
program that enables a computer to transmit data over, for example, telephone
or cable lines. Computer information is stored digitally, whereas information
transmitted over telephone lines is transmitted in the form of analog waves. A
modem converts between these two forms.
The process of recovering
the original signal from the modulated wave is known as demodulation or
detection. ... When the modulated wave is picked up by the radio receiver, it
is necessary to recover the audio signal from it. This process is accomplished
in the radio receiver and is called demodulation.
