Question

What is meant by phase, amplitude, modulation and frequency?

Answer 1

Phase: The phase of an alternating quantity is defined as the divisional part of a cycle through which the quantity moves forward from a selected origin.

Amplitude: Amplitude is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

Modulation: Modulation is a process through which audio, video, image or text information is added to an electrical or optical carrier signal to be transmitted over a telecommunication or electronic medium. Modulation enables the transfer of information on an electrical signal to a receiving device that demodulates the signal to extract the blended information.
Frequency: Frequency is the number of waves that pass a fixed point in unit time.
