CHAPTER 4 COMMUNICATION SYSTEMS. Noise factors that affect communication are more than simply loud noises. The term refers to many kinds of roadblocks or types of interference that prevent people from effectively exchanging messages. Some noise factors are easily managed, but others are difficult to overcome., impact of noise on communication systems, from the early 1920s to the monumental work of Edwin H.

system is, how well formed and well developed it is, barriers do occur within the communication systems, whether it is an organization, communication between the family members, social network If noise exists in these elements in any way, complete clarity of meaning and understanding does not occur. The author, George Bernard Shaw wrote, ‖The greatest problem with communication is the illusion that it has been accomplished‖ (Shaw, 2011). Four types of barriers (called ―noise,‖ see Figure 1) are process barriers, physical

A duplex communication system is a system composed of two connected parties or devices which can communicate with one another in both directions. The term duplex is used when describing communication between two parties or devices. Duplex systems are employed in nearly all communications networks, either to allow for a communication "two-way system is, how well formed and well developed it is, barriers do occur within the communication systems, whether it is an organization, communication between the family members, social network

This is the noise voltage found at the terminals of a resistor; it sets a lower boundary on the noise voltage from any resistive source. Notice that a perfect conductor has no thermal noise. Thermal noise in a practical system is limited by the bandwidth of the system but is small. For Efficiency of communication system reduces Types of noise Thermal noise/white noise/Johnson noise or fluctuation noise Shot noise Noise temperature Quantization noise Thermal Noise: This noise is generated due to thermal motion (Brownian motion) of electrons inside resistor. This noise is zero at absolute zero degree Kelvin and generated when
