gKit 32. TWO STAGE FM TRANSMITTER This Kit is a powerful two stage‚ 9V FM transmitter (Tx) with a range of up to 1 kilometer in the open. It uses an RF transistor in its output stage. Distance of transmission is critically dependent on the operating Conditions (in a building or out on the open)‚ type of aerial used (single wire or dipole)‚ operating voltage (12V is better than 6V) and if the circuit is peaked for maximum performance. The kit is constructed on a single-sided printed circuit board

Abstract- Driverless cars are the promising approach to reduce the traffic problems. In driverless cars the frequently changing state of the road due to obstacles is controlled by array of sensors‚ which acknowledges the presence of obstacles on the driving path and creates the suitable path by frequently updating the route. This paper describes the efficient Doppler radar system and specialized algorithms to measure the speed of a vehicle used in autonomous vehicles. The velocity‚ acceleration and

Upon researching the current Plain Old Telephone Service (POTS) that the company is currently using the following components‚ Local Loop‚ Central Office‚ Local Exchanges‚ POP‚ Long Distance System‚ and Fixed Line. A brief description of each components are as follows: a Local Loop is a simple network that connects a home to the Central Office of the Telephone Company. It consists of twisted pair cables with a maximum length of three miles. The Central Office is an office in a locality to which a

the use of antenna arrays in interference cancellation and for receive diversity. This final chapter takes a broad view of the use of antenna arrays in wireless communications. In particular‚ we will investigate the capacity of systems using multiple transmit and/or multiple receive antennas. This provides a fundamental limit on the data throughput in multipleinput multiple-output (MIMO) systems. We will also develop the use of transmit diversity‚ i.e.‚ the use of multiple transmit antennas to achieve

really top-of-the-world view of Toronto. But many people don’t consider the CN tower to be a building‚ since it does not contains occupied floors throughout its full height. People disagree on whether things like telecom towers‚ flagpoles‚ antennas‚ and spires should be included when measuring a building’s height. They say that buildings are used for offices and apartments‚ but structures are not–they do not have residential or office space. Are observation towers buildings or structures? What

the title of the tallest man-made structure in the world‚ a title it held for 41 years‚ until the Chrysler Building in New York City was built in 1930. However‚ due to the addition‚ in 1957‚ of the antenna atop the Eiffel Tower‚ it is now taller than the Chrysler Building. Not including broadcast antennas‚ it is the second-tallest structure in France‚ after the Millau Viaduct.The tower has three levels for visitors. Tickets can be purchased to ascend‚ by stairs or lift‚ to the first and second levels

CHAPTER 1 THE PROBLEM AND ITS BACKGROUND Introduction The changing needs of people led to the development of a means to make tasks a lot easier and more convenient. This is technology. It is a tool that now plays an important role in people’s everyday life. Because of this technology every complicated task is now provided with an equal solution. Hence‚ the difficulties that people experience in doing tasks are minimized. It is not impossible that in the near future‚ these difficulties will be

In this paper‚ we consider an nt -antenna at the source S‚ an nr -antenna at the relay R and nd -antenna at the destination D‚ where the propagated signal from the source passes through keyhole and correlated channel. The same orthogonal space time block codes (OSTBC) is applied to source -destination‚ sourcerelay and
