noise is an undesired and unwanted sound or singnal in communication
white noise
Harmfull Effect: the harmfull effect of noise in a communication system is the it weeks the strength of the massage single.
Noise may interfere with signal at ant point in a communication system.The noise has its greatest effect on the signal in the channel.
in the channel only
Internal noise is due to the thermal agitation of the atoms in the electrical components of communication system.
The word 'Noise' in communication theory is a barrier to communication that may weaken or destroy a message that is trying to be relayed There are a number of ways to classify noise. It can be subdivided according to type, source, effect, or relation to the receiver, depending on circumstances. In order to make the classification more compact, noise sources can be divided into two main groups: • Noise whose sources are external to the receiver (External Noise) and • Noise source created within the receiver itself (Internal Noise). types include: Shot noise; Johnson noise; Partition noise and White noise
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.

Sound is noise in communication
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.
