differences between analog and digital communication systems

Advantages - The advantages associate with digital communication systems include (i) A common format for encoding different kinds of message signals (e.g., speech signal, video signal, computer data, etc.) for the purpose of transmission. (ii) An improved sec..

Analog and Digital Communication - The concept of information is central to communication. There is no precise definition of the word "information". So, instead of information, we deal with "message". Message is defined as the physical manifestation of inform..

. A good quality service can be continuously ensured by a global operational satellite system. Thus, communication satellites would give a valuable service in addition to the submarine cable and high frequency radio systems. Geostationary communication satell..

Summary - While the nervous system and endocrine system have their own features, they have a common method of communication. Both the systems release chemicals to communicate between cells. Together these two systems carry out a very compl..

Importance of Radio Waves in Modern Communication - Radio waves are electromagnetic waves of wavelength 10 - 3 m and higher. Their frequency range is from a few kHz to nearly a few hundred MHz. The propagation of radio waves through the atmosphere is relevant in all modern forms of c..

) cannot be efficiently radiated and do not propagate well in space. (ii) Simultaneous transmission of different signals by different transmitters would lead to confusion at the receiver. In order to solve these problems; we need to devise methods to convert or translate the aud..

International System of Units - In 1960, the Eleventh General Conference of Weights and Measures recommended an International System of Units (abbreviated as SI) based on the metric system of measurement. When the recommendation was accepted in 1968, it marked the firs..
