The three elements of a carrier wave that can be manipulated are:
Amplitude: The amplitude of a carrier wave refers to the maximum displacement or height of the wave from its equilibrium position. It represents the strength or intensity of the wave. By manipulating the amplitude of the carrier wave, you can control the strength or power of the signal that is being carried.
Frequency: Frequency refers to the number of complete cycles or oscillations of the carrier wave that occur per unit of time. It is typically measured in hertz (Hz). By manipulating the frequency of the carrier wave, you can control the rate at which the signal is transmitted.
Phase: Phase represents the position or state of the carrier wave at a specific point in time, usually measured in degrees or radians. Manipulating the phase of the carrier wave involves shifting the starting point or position of the wave. Phase modulation is commonly used in various communication systems to encode and transmit information.
By manipulating these three elements—amplitude, frequency, and phase—you can modulate or vary the carrier wave to carry information. This modulation technique allows the superimposition of the desired information signal onto the carrier wave, enabling the transmission of data through modulation schemes like amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM).
