What is meant by the term modulation?

Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height, or amplitude, and frequency.

What is modulation and example?

For example, the modulation signal might be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal representing a sequence of binary digits, a bitstream from a computer. The carrier is higher in frequency than the modulation signal.

What is meant by 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 of the carrier. A modem is an equipment that performs both modulation and demodulation.

What does the modulation term mean in communication?

Modulation is the process of encoding information from a message source in a way that is suitable for transmission. ... By superimposing a message on to a high frequency signal known as a carrier wave (or sinusoidal signal), video, voice and other data can be transmitted.
