...------------------------------------------------- ------------------------------------------------- Microwave an RF Supplementary Project ------------------------------------------------- Equivalent Impedance of an Antenna Introduction: Antenna impedance is a measure of the resistance to an electrical signal in an antenna. Many factors have an impact on an antenna’s ability to transmit a signal, including the environment that the antenna is in and the design and composition of the antenna. Understanding antenna impedance is important when designing components that connect an antenna to a receiver or transmitter. The ratio to voltage current, which is equal to antenna impedance, is expressed in ohms. The antenna impedance represents the power that is absorbed by the antenna as well as the power that is dispersed by it as it comes into contact with electromagnetic waves. Voltage and Current Relationship: Antenna impedance relates the voltage to the current at the input to the antenna. Let us assume that the antenna has an impedance of 50 ohms. And if a sinusoidal voltage is applied at the antenna terminals with amplitude of 1 volt, then the current will have amplitude of I=VR=150=0.02 A. Since the impedance is a real number, the voltage is in phase with the current. Alternatively suppose the impedance is given by complex number say Z=50+j50 ohms. If Z=50+j50, then the impedance has the magnitude equal to: 502+502=70.71 The phase will be equal to: tan-1ImZReZ=45° ...

...Executive Summary Tivo’s new consumer electronics product has the potential to revolutionalize media consumption habits and the structure of the television industry. The key challenges include: (i) how to improve the value of the product in terms of the benefit to cost ratio and (ii) how to increase awareness of the brand as well as the many different product attributes. We recommend that (i) TiVo improve the value of the product by unbundling it in terms of the various benefits provided and then bundling the individual components with other complementary products. (ii) So as to increase the awareness of the different TiVo products and the brand, we propose to segment the market in terms of the specific customer profile whose needs are aligned to the particular benefit provided by the product. Accordingly, we arrive at a communication plan for the different TiVo products that target different customer segments through a mix of advertising, promotion, distribution and branding strategies. In the following section, we analyze the situation that Tivo is faced with and follow it up with the logical sequence that helped us arrive at the above recommendations. Company Analysis Calyx and Corolla is a new company in the fresh flowers market. They have pioneered the concept of selling fresh flowers by mail. In its short lifetime, C&C has established strong relationships with many large growers, who cut flowers when ordered, thereby increasing the life of the buds tremendously...

...major concepts of the motherboard include; peripherals, Interface cards, daughter cards: sound cards, video cards, network cards, hard drives, TV tuner cards, cards providing extra USB or FireWire slots and a variety of other components. A peripheral is a device that is used to put information into get information out of the country. The Daughter cards or daughterboard contains plug sockets connectors for other boards to attached to. Daughterboards only have internal connections. Next is the sound cards. The sound cards is an internal computer expansion card. It facilitates economical input of auto signals to and from a computer found under control of a computer programs. Video cards is a type of expansion card this also generates a feed of output images to the display. They are frequently advertised as dedicated graphics cards. Which is a big difference between the integrated graphics. Sometimes video cards are called graphic add- in- boards. Network cards is a computer hardware component that connects a computer to a computer network. (Wi-Fi connection) The hard drives is a data storage device used to store and retrieving digital information using one or more rigid(hard) rapidly rotating disks platters coated with megnetic material. TV tuner card is a kind of television that allows TV signals to be retrieved by a computer. Most TV tuners function as video capture cards which allows them to record TV programs onto a hard disk, much like the DVR does. Next is USB, for Universal serial...
