Question

What type of modulation is used for continuous and sinusoidal waves?

Answer 1

Hint : In order to answer this question, first we will mention the types of modulation used for continuous and sinusoidal waves, and then we will also discuss the modulation types separately. We will discuss more about continuous and sinusoidal waves.

Complete Step By Step Answer:
Amplitude modulation, Frequency modulation and Phase modulation are used for the carrier wave which is a continuous wave whereas Pulse amplitude modulation, Pulse width modulation and Pulse position modulation is used if the wave is not a continuous one and is in the form of pulses.
Amplitude modulation is a method of transmitting a wave signal by changing the amplitude of the signal. It's generally referred to as AM, and it's a method of transferring data over a radio carrier wave. The most common application of amplitude modulation is in electronic communication.
Frequency modulation is a method of encoding information on a signal (analogue or digital) by shifting the carrier wave frequency in line with the modulating signal's frequency. A modulating signal is simply information or a message that must be conveyed after being turned into an electronic signal, as we all know.
Phase modulation is a sort of angle modulation in which the carrier signal's total phase angle varies in proportion to the message signal's amplitude. or The method of delivering information over a carrier wave by shifting the phase in line with the amplitude of the message signal is known as phase modulation.

Note :
A sine wave, also known as a sinusoidal wave, is a smooth, repeated oscillation described by a curve. The sine wave is defined as "a wave shape whose amplitude is always proportional to the sine of its displacement angle at all points in time." By combining sine waves, any wave can be created. The sine wave has a pattern that repeats itself.
