Communication (from Latin "communis"‚ meaning to share) is the activity of conveying information through the exchange of thoughts‚ messages‚ or information‚ as by speech‚ visuals‚ signals‚ writing‚ or behavior. Communication is defined by de Valenzuela as “any act by which one person gives to or receives from another person information about that person’s needs‚ desires‚ perceptions‚ knowledge‚ or affective states. Communication may be intentional or unintentional‚ may involve conventional or unconventional

Remote. A player places a sensor bar‚ which contains two infrared transmitters‚ near or on top of a television. While the player uses the Wii Remote‚ the Wii game console determines the remote’s location by calculating the distance and angles between the Wii Remote and the two transmitters on the sensor bar. Determining the location of a Wii Remote is relatively simple because the sensor bar contains only two fixed points: the transmitters. A more complex application of triangulation occurs in a global

These units could only transmit from a single sensor channel‚ and were difficult to assemble due to the use of discrete components. The measurement parameters consisted of temperature‚ pH or pressure‚ and the first attempts of conducting real-time noninvasive

Intra-body Communication using Personal Area Network Abstract Intra-body communication is a "wireless" communication technique that enables electronic devices on or near the human body to exchange the information. For this the characteristics of the human body are studied. The human body acts as a signal transmission medium and it uses the dielectric properties of human tissues for data exchange which covers frequency range from 100 KHz to 150MHz. Transmitting data directly through the skin can

Figure 1.1 illustrates discrete data transmission‚ which is the transmission of one message from a finite set of messages through a communication channel. A message sender at the transmitter communicates with a message receiver. The sender selects one message from the finite set‚ and the transmitter sends a corresponding signal (or “waveform”) that represents this message through the communication channel. The receiver decides the message sent by observing the channel output. Successive transmission

Doordarshan is of the largest broadcasting organisation in the world in terms of the infrastructure of studio and transmitters‚ the variety of software and the vastness of the viewership. The experimental telecast started in Delhi in September 1959 with a small transmitter and a market shift studio and regular daily transmission started in 1965. Television was separated from radio in 1976 and Doordarshan came into existence‚ from then onwards

The transmitter section continuously transmits IR rays which are received by the receiver section. The received signal is further amplified and given to the PLL section‚ where its frequency is locked to the transmitted frequency. When the IR signal is interrupted
