YAGI-UDA ANTENNA Dr. Shintaro Uda and Dr. Hidetsugu Yagi of the Tohoku Imperial University invented a directional antenna system consisting of an array of coupled parallel dipoles. Yagi-uda or simply yagi antennas or yagi’s are the most high gain antennas. It consists of a driven element‚ a reflector and one or more directors. i.e.‚ yagi uda antenna is an array of a driven element and one or more parasitic elements. The driven element is a resonant half wave dipole usually of metallic rod. The

Matthew Anderson NT1310 October 1‚ 2014 Unit 3 Assignment 1 “A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu‚ 2013). There are several common instances of the bus architecture‚ including one in the motherboard of most computers. Bus networks may be the simplest way to connect multiple clients even though many may have problems. When two clients want to transmit at the same time on the same bus‚ this may cause

late 1960’s‚ the company had increased its business to include data transmission equipment. The company had a reputation of being a source of high quality innovative designs and described itself as being able to “convert problems to solutions” in their sales brochures. By 1978‚ two major lines were recognized: broadcast equipment and data transmission. Broadcast equipment accounted for 35% of the company sales. Data transmission was also blossoming with increased demand for highly specialized and

ABSTRACT In the world of technology‚ Universal Serial Bus (USB) is a serial bus standard to connect devices to a host computer. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve plug and play capabilities by allowing hot swapping; that is‚ by allowing devices to be connected and disconnected without rebooting the computer or turning off the device. Other convenient features include providing power to low-consumption devices‚
