What are the advantages and disadvantages of noise in a communication system?
Harmfull Effect: the harmfull effect of noise in a communication system is the it weeks the strength of the massage single.
A communication channel with additive white gaussian noise has a bandwidth of 4kHz and SNR of 31dB. Its channel capacity is?
20kbps
What are the disadvantages of analog communication?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference.
What are the Advantages of analog and digital communications?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference. Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization. Advantage of Digital Communication: 1)Digital Communication systems are simpler and cheaper. 2)Using data encryption only permitted user are allowed to detect the transmitted data. 3)Since in Digital Communication, channel coding is used, therefore a large amount of errors may be detected 4)Since transmitted signal is digital in nature,large amount of noise tolerance may be tolerated Disadvantage of Digital Communication: 1)More transmission bandwidth required. 2)Digital Communication needs synchronization in case of synchronous modulation.
What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
In a communication system noise is most likely to get into the system?
in the channel only
In a communication system noise is most likely to affet the signal at?
channel
Where does noise enters in a communication system?
Noise may interfere with signal at ant point in a communication system.The noise has its greatest effect on the signal in the channel.
What is noise in communication system and the source of the noise?
noise is an undesired and unwanted sound or singnal in communication
What colour of noise is harmful for communication system?
white noise

A communication channel with additive white gaussian noise has a bandwidth of 4kHz and SNR of 31dB. Its channel capacity is?
20kbps
Which communication system reserves channel 16 as a calling and distress channel?
The VHF marine radio communication system reserves channel 16 as a calling and distress channel. This channel is used for initiating communication and for broadcasting distress signals in case of emergencies at sea.
When an electronic mail system is installed as part of the communication system what element of the communication process is changed?
channel
Examples of internal noise in communication?
Internal noise is due to the thermal agitation of the atoms in the electrical components of communication system.
What are the disadvantages of analog communication?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference.
What is noise in communication?
Sound is noise in communication
