    OPTICAL AMPLIFIER An optical amplifier is a device that amplifies an optical signal directly‚ without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity‚ or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. There are several different physical mechanisms that can be used to amplify a light signal‚ which correspond to the major types of optical

    1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The environmental factors that you are testing on the rate of transpiration are the independent variable of this experiment. These independent variables are specifically light‚ fan‚ dark‚ and humidity. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants are things like the type of plant used‚ room

    Q1. Various digital-to-digital encoding techniques are as follows: a) Signal spectrum – a transmission contains lack of high frequency components which means less bandwidth is required and direct current component is also desirable. With no dc component‚ ‘ac’ coupling via transformer is possible. Finally‚ the magnitude of the effects of signal distortion and interference depend on the spectral properties of the transmitted signal. b) Clocking – to provide a separate clock lead to synchronize the

    1) What is Electro-Plating? Electroplating is the process of coating a metal object with a thin layer of another metal by means of electrolysis.  2) What is Copper Plating? Copper plating is a coating of copper metal on another material‚ often other metals. Plating is designed to increase durability‚ strength‚ or visual appeal‚ and copper plating specifically is often used to improve heat and electrical conductivity. 3) What are the uses of electro-plating/copper plating?

Due to the problem‚ this company need to determine how the background traffic is affecting the FTP traffic on the network. So‚ this analysis is to compare the FTP performance on the network under two scenarios. First is network without background traffic and‚ second is the scenario with background traffic.

    Optical Activity of Carvones Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/29/03 Abstract: The objective of this experiment is to use Gas Chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and to find the 2 carvone’s optical activity as well as percent carvone in spearment and caraway oil. It was found that S-carvone had an optical activity of 0.0047 and R-carvone had an optical activity of 0.516 and that spearment oil is 59%

    [pic] An optical illusion also called a visual illusion is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them‚ physiological ones that are the effects on the eyes and brain of excessive stimulation
