Question

what is modulation ... ??....​

Answer 1

Answer:

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted.

Answer 2

1. Modulation is that the method of changing information into radio waves by adding data to Associate in Nursing electronic or optical carrier signal.
2. A carrier signal is one with a gradual wave constant height, or amplitude, and frequency.
3. Modulation is that the method of changing information into electrical signals optimized for transmission.
4. Modulation is that the act or method of giving a wave or signal the amplitude or frequency of another wave or signal.
5. As we know that in telecommunications, modulation is that the method of conveyancing a message signal, as an example, a digital bitstream or Associate in Nursing analog audio signal, within another signal that may be physically transmitted.

Following are the Modulation techniques are roughly divided into four types:

1. Analog modulation,
2. Digital modulation,
3. modulation,
4. unfold spectrum technique.
