In Pulse Code Modulation (PCM), if the transmission path is very long, the signal may be subject to degradation due to factors such as attenuation, noise, and interference. To mitigate these effects, repeaters can be used to amplify the signal at intervals along the path. Additionally, error detection and correction techniques can be implemented to ensure data integrity. Ultimately, careful consideration of the transmission medium and encoding techniques is crucial for maintaining signal quality over long distances.
What else can I help you with?
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
Role of modulation in signal transmission is varying why?
The Role of modulation in signal transmission varies because of what type of signal should be modulated.Then how long it should be travel in air.All these points are considered, when we go before modulation.Suppose we are transmitting vedio signal means it should be only Amplitude Modulated signal.If we transmitting audio signal means it should be Frequency Modulated Signals.So the Role of the modulation is varies in signal transmission.
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).
Need of modulation in communication?
Need for modulation: 1. Length of the antenna for a transmitter is inversly proportional to the frequency of the signal to be transmitted. So we try shift the frequency of the singal for the transmission to higher frequencies. 2. Every transmission of signal in a bandwidth is assigned with a particular frequency which is attained by modulating the signal with the carrier frequency. Different modulation techniques are implemented according to the requirements and compatibilities
What is message signal in amplitude modulation?
In amplitude modulation (AM), the message signal is the original audio or information signal that contains the content to be transmitted, such as voice, music, or data. This signal is typically a low-frequency waveform that varies in amplitude. The message signal modulates the amplitude of a higher frequency carrier wave, which translates the information for efficient transmission over long distances. The result is a modulated wave that carries the original message signal within its amplitude variations.
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.

An electric current that is varied to represent information is what?
An electric current that is varied to represent information is called a modulated current. This modulation can take various forms, such as amplitude modulation (AM), frequency modulation (FM), or pulse modulation, and is commonly used in telecommunications to transmit data over long distances efficiently.

What is modulation and how is it used in communication systems Can you provide two examples of how modulation is utilized in modern technology?
Modulation is the process of varying a carrier signal's properties, such as amplitude, frequency, or phase, to encode information for transmission. In communication systems, modulation is used to efficiently transmit data over long distances by converting the information into a form that can be carried by the carrier signal. Two examples of how modulation is utilized in modern technology are: In Wi-Fi technology, modulation techniques like Quadrature Amplitude Modulation (QAM) are used to encode digital data into radio waves for wireless communication between devices. In digital television broadcasting, modulation methods such as Vestigial Sideband Modulation (VSB) are employed to transmit audio and video signals over the airwaves for high-quality TV reception.
What is Modulation and what is the aim of modulation?
Modulation is any of several means of encoding an information carrying signal onto a carrier of fixed frequency. The purpose is to allow the information to be transported long distances.
