Why digital signal processing is needed?
Digital Signal Processing is important because it significantly increases the overall value of hearing protection. Unlike passive protection, DSP suppresses noise without blocking the speech signal. Real world signals are converted into a domain where abstract scientific and mathematical models are then applied.
Why is digital communication better than analog communication?
The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are more reliable. The configuring process of digital signals is easier than analog signals. Digital signals can be saved and retrieved more conveniently than analog signals.
What are the advantages and limitations of digital signal processing?
➨DSP offers very high accuracy. Hence filters designed in DSP have tighter control on output accuarcy compare to analog filters. ➨The digital implementation is cheaper compare to analog counterpart. ➨The reconfiguration is difficult in analog system as entire hardware and its components need to be changed.
What is the main advantage of digital signals over analog signals?
Advantages of Digital Signal Over Analog Signal Digital signals are more secure, and they do not get damaged by noise. They allow the signals transmitted over a lengthy distance. By using these signals, we can translate the messages, audio, video into device language.
What is optoptical fiber communication?
Optical Fiber Communication is the method of communication in which signal is transmitted in the form of light and optical fiber is used as a medium of transmitting those light signal from one place to another.
How does optical fiber transmit data?
The signal transmitted in optical fiber is converted from the electrical signal into light and at the receiving end, it is converted back into the electrical signal from the light. The data sent can be in the form of audio, video or telemetry data that is to be sent over long distances or over Local Area Networks.
What are the advantages of optical fiber cable?
Bandwidth – Single laser light dispersion means that a good amount of signal can be transmitted (Information being transferred in bits) per second which results in high bandwidth for long distances. Smaller diameter – The diameter of Optical fiber cable is about 300 micrometers in diameter.
What type of light is used for optical fiber communication?
Light or Laser light (to be precise) is used for the optical fiber communication because of the reason that the laser light is a single wavelength light source.
