Question

what is modulation..?​

Answer 1

Answer:

what is modulation..?

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted. Most radio systems in the 20th century used frequency modulation (FM) or amplitude modulation (AM) for radio broadcast.

Why do you need modulation?

Modulation allows us to send a signal over a band pass frequency range.

Answer 2

Modulation

• The process of turning data into electrical impulses optimized for transmission is known as modulation.
• The goal of modulation is to imprint information mostly on a carrier signal, which is then utilized to transport the information to some other location. 
• The goal of modulation is to imprint information mostly on a carrier wave, which will then be utilized to transport the information to some other point.
• In radio transmission, the modulating carrier gets transmitted like a radio signal through space toward a radio receiver.
