Channel noise in communication systems is the crackling or high-pitched noises you get in addition to what you want to hear. It is often caused by external electronic interference.
Harmfull Effect: the harmfull effect of noise in a communication system is the it weeks the strength of the massage single.

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.
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.
An AWGN channel adds white Gaussian noise to the signal that passes through it.

Noise may interfere with signal at ant point in a communication system.The noise has its greatest effect on the signal in the channel.
noise is an undesired and unwanted sound or singnal in communication

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.

Internal noise is due to the thermal agitation of the atoms in the electrical components of communication system.
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.
