What OSI physical layer term describes the process by which one wave modifies another wave?
Answers Explanation & Hints:
Modulation is the process by which a signal, called the modulating signal, is used to modify another signal, called the carrier signal. The modulating signal contains the information that needs to be transmitted, while the carrier signal provides the means to transmit this information over a communication channel.
In modulation, the modulating signal is combined with the carrier signal in such a way that it alters one or more of the properties of the carrier signal, such as amplitude, frequency or phase. The resulting signal, called the modulated signal, contains the information from the modulating signal and can be transmitted over a communication channel.
At the receiving end, the modulated signal is demodulated to recover the original modulating signal. Demodulation is the process of extracting the modulating signal from the modulated signal by reversing the process of modulation.
Modulation is a fundamental concept in communication systems, and it is used in many different types of communication systems, such as radio, television, mobile phones, and computer networks.
