message transmission through the channel. Dependencies between message transmissions can be important also‚ but the study of such inter-message dependency is deferred to later chapters. The messages are usually digital sequences of bits‚ which are usually not compatible with transmission of physical analog signals through a communication channel. Thus the messages are converted into analog signals that can be sent through the channel. Section 1.1 introduces both encoding and modulation to characterize

NOISE IS A BARRIER Noise is indeed a barrier to communication‚ it is unavoidable and prevalent in just about every environment. Some types of noise are: * physiological noise - this includes hearing disorders‚ impairments and disabilities that make it difficult to send or receive messages‚ for e.g. deafness * semantic noise – the unintended meanings aroused by the use of certain behaviours or symbols that distract your

How organization’s overcome environmental changes? Organisations need to deal with environmental changes with appropriate strategies. First‚ organisations may choose to wait and see. Such strategy has its advantages and disadvantages. For example‚ facing a significant technological change‚ some companies may choose to integrate the new technology into their products. If they are successful‚ the rest companies’ ‘wait and see’ strategy is obviously unwise. However‚ if they failed‚ the rest companies’
