Information Theory

Ass.Prof.Dr. Thamer Information theory 4th class in Communications Error Detection and Correction 1. Types of Errors Whenever bits flow from one point to another, they are subject to unpredictable changes because of interference. This interference can change the shape of the signal. In a single-bit error, a 0 is changed to a 1 or a 1 to a 0. The term single-bit error means that only 1 bit of a given data unit (such as a byte, character, or packet) is changed from 1 to 0 or from 0 to 1. The term...

Cause And Effect Of Computer Addiction

amplitude which is generally carried by use of modulation. 2. History of Analog Communication – 3. Amplitude Modulation - Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength (amplitude) of the carrier in proportion to the waveform being sent. 4. Angle Modulation - is a class of analog modulation. These techniques are based on altering the angle (or phase)...

DIGITAL Signal PROCESSING DIGITAL SIGNAL PROCESSING refers to manipulating analog information, such as sound or photographs that has been converted into a digital form. DSP also implies the use of a data compression technique. DSP refers to various techniques for improving the accuracy and reliability of digital communications. The theory behind DSP is quite complex. Basically, DSP works by clarifying, or standardizing, the levels or states of a digital signal. ADSP circuit is able to differentiate...

Meeting Is The Most Effective Direct Communication Channel Analysis

Depending on how the meeting is named it will create a certain reaction among the co-workers, he further discusses. For example, calling the personnel to an information meeting, they expect to receive information that may be of interest. Yet, calling them to a work meeting may result in a high absence, as these often lack of important information and are viewed as a bit fuzzy, he adds. Yet, personal meetings do not have to be of such formal character, according to Högström et al (1999, pp. 92-93), but...

Word of Mouth Marketing

of certain products. The research of this article focuses on the manner in which the information was provided and presented, along with the type of evidence that’s available for processing. Their goal was to investigate the word of mouth effects on persuasion and to identify other moderating variables. One of the factors they used to mediate the effects of word of mouth was information vividness. Information vividness is interesting, attention drawing, and thought provoking which usually has a...

Phase Shift Keying Analysis

1.4.1 FREQUENCY SHIFT KEYING (FSK) Frequency shift keying is a frequency modulation in which the digital information is transmitted by discrete changes in frequency of the carrier signal. This technology is used for the communication system such as caller ID and emergency broadcasts [19]. The binary FSK is the simplest FSK. BFSK uses a pair of discrete frequencies to transmit binary information. The 1 and 0 is mentioned as mark frequency and space frequency. The other forms of FSK are Continuous-phase...

Communication Process

largely on the kind of channel been used. The flow of communication process is very important to the success of any organization; it is a part of almost everything that happens on a daily basis in an organizational environment. The advancement of information technology has brought so many communication channels that are use within an organization. In my workplace, we use so many means of communication; the most successful is the face-to-face, telephone and sometime electronic emails while the unsuccessful...
