Amplitude Modulation (AM) and Frequency Modulation (FM) are commonly used for sound signals. AM varies the amplitude of the carrier wave to encode the audio information, making it simple and effective for broadcasting over long distances. FM, on the other hand, varies the frequency of the carrier wave, providing better sound quality and resistance to noise, which is why it is often preferred for music and high-fidelity audio transmission. Both methods allow for efficient transmission of audio signals over radio waves.

Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.

What is light modulation?
Light modulation refers to the process of varying a light signal's properties, such as its intensity, frequency, or phase, to encode information. This technique is widely used in telecommunications, such as in fiber optic communication, where data is transmitted over long distances. Modulation allows for efficient transmission and improved signal quality by adapting the light signal to different conditions and requirements. Common methods of light modulation include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).
Can laser beam be used as RF signal carrier?
When modulated with a radio frequency signal, they will indeed carry information. As in fibre-optic cables. The modulation may be of the several commonly used types, amplitude, frequency, phase ... modulation.
What is the carrier signal used for pulse modulation?
In pulse modulation, the carrier signal is typically a continuous analog waveform, such as a sine wave or square wave, that serves as the basis for transmitting information. The modulation process involves varying certain properties of this carrier wave—such as its amplitude, width, or position—according to the information signal. This modulation allows the information to be encoded and transmitted efficiently over various communication channels. Common types of pulse modulation include Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), and Pulse Position Modulation (PPM).

What type of modulation is used in tv transmission?
Television transmission primarily utilizes amplitude modulation (AM) for the video signal and frequency modulation (FM) for the audio signal. In analog TV, the video is modulated using AM, while the accompanying audio is transmitted using FM to provide better sound quality and resistance to noise. In digital TV, various modulation techniques such as 8VSB (for ATSC) or COFDM (for DVB) are used to efficiently transmit data over the airwaves.

What do understand by frequency modulation?
It means that there is a base wave, and that the frequency is changed to transmit a signal. For example, if you want to transmit a signal representing a 1000 Hz sound, the frequency of the base wave would be increased and decreased a thousand times in a second.
