CHAPTER-1-INTRODUCTION 1. INTRODUCTION TO WIRELESS PC COMMUNICATION In many situations a communication link between two devices becomes essential. This communication can be wired or wireless. If two devices are close to each other a wired link is preferred. However in many situations two devices are reasonably far apart. In that case a wireless link is preferred. One of the popular wireless communication technologies is RF communication that is being used in our project. The HT12E and HT12D

our day to day life. For communication of information and messages we use telephone and postal communication systems. Similarly data and information from one computer system can be transmitted to other systems across geographical areas. Thus data transmission is the movement of information using some standard methods. These methods include electrical signals carried along a conductor‚ optical signals along an optical fibers and electromagnetic areas. Suppose a manager has to write several letters to

• Features • Application Fields ABSTRACT “Red Tacton” gives a whole new meaning to the term “networking”. It is a new personal area networks technology which uses the surface of the human body‚ as a safe data transmission path‚ at speeds up to 10 Mbps. Red Tacton does not rely on electromagnetic or a light wave to transmit data. It makes use of weak electric fields on the surface of the body. Using a new super-sensitive photonic electric field sensor

EE213 Electrical Circuits Laboratory Term Project Two Speed Automatic Transmission System 1. Introduction Transmission system is an assembly of gears‚ shafts and electrical gadgets in an automobile. This system forms a bridge between the engine and wheels to transmit mechanical power required for movement. The complete set up reduces the high rotational speed of engine to lower wheel speed‚ since internal combustion engines in automobiles operate between 600 and 7000 revolutions per minute (rpm)

One out of every ten cars sold in the United States has a manual transmission. Being able to operate a manual transmission is a very important skill to have available. There are many reasons that manual transmission cars are the better choice to drive‚ but the only downfall that manual transmissions have is that the learning curve when starting out can be hard to get used to. What makes operating a manual transmission harder is that there is a third pedal‚ and you can stall out your car. Once the

They work on the principle of oscillation which is a periodic fluctuation between the maximum and minimum value of the quantity. Oscillators mainly consist of two parts: the active circuit and the resonator. In active circuit there are active circuit elements

SCOPE Background The objective of the EE1003 project is to understand basic concepts in signal processing and transmission by implementing a one-way voice communication system. In this project‚ audio digital signal is transmitted from the transmitter side to the receiver side via a laser link. Subsequently‚ the received signals will be played back using a speaker. The system is illustrated in Figure 1. Figure 1 Project illustration Firstly‚ the project requires to encode the input analog
