flows electrical current. In data communication‚ a circuit is considered as a specific path that is between two or more end points that carries along a signal that can be either analog or digital. The physical path of the circuit may consist of one or more wires and can also be wireless as well. The difference between a circuit and a channel is basically the way that it is utilized. A channel is a portion of the circuit that is used to transmit a single voice or data signal‚ which can be either

stream for transmission over a single digital communication channel: Time slots Multiplexer Demultiplexer EE4512 Analog and Digital Communications Chapter 7 • The TDM time slots have to be chosen properly. If the time slots are too small (for example‚ 1 bit) then the multiplexer and demultiplexer must switch rapidly. If the time slots are too large (for example‚ 64 Kb) then the data must be buffered and delay would be produced. TDM is used for baseband (not bandpass) data transmission

Abstract: VLSI based Accident information and car security system deals with the concern of saving the victim ‚ who get trapped in accident and also about the car security. Accident of the car is detected using pressor sensors which are fixed in car. Accident information to the nearest hospital is carried out with the help of RF communication. The location of the car is found using the GPS technique. The security of car is ensured by using password. The theft information is sent to the owner’s mobile

spaces such as meeting rooms and auditoriums filled with people and communication is not secure because signals can be intercepted. Technology for solving such problems includes the use of the person body as a signal path for communication. A transmission path is formed automatically when a person comes into contact with a device and communication between mobile terminals begins. Table of Contents 1.

a. Flow control It is the process of managing the rate of data transmission between two nodes to prevent a fast sender from outrunning a slow receiver. It provides a mechanism for the receiver to control the transmission speed‚ so that the receiving node is not overwhelmed with data from transmitting node. Flow control should be distinguished from congestion control‚ which is used for controlling the flow of data when congestion has actually occurred. Error control It is the process of detecting

services‚ the main target of HSDPA is to increase user peak data rates‚ quality of service‚ and to generally improve spectral efficiency for downlink asymmetrical services. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps(megabits per second). Though any data can be transmitted‚ applications with high data demands such as video and streaming music are the focus of HSDPA. Hence by implementing HSDPA in wifi hotspots theoretical data rates of about 10 Mbps can be achieved even in wifi hotspots
