1. Define Modulation Modulation process of putting information onto a high-frequency carrier for transmission. 2. What is carrier frequency? In essence‚ then the transmission takes place at the high frequency (the carrier) which has been modified to “carry” the lower-frequency information. 3. Describe the two reasons that modulation is used for communications transmission. The modulated stage accepts two inputs‚ the carrier and the information (intelligence) signal. 4

Purpose: The purpose of these experiments[1] was to measure the exciting current and determine the core losses in a transformer using the open circuit test (experiment # 2) and to determine the equivalent circuit of a transformer by using the short circuit method (experiment # 3). Introduction: In order to determine the equivalent circuit parameters of a transformer two simple tests are used‚ namely the open-circuit test (experiment #2) and the short-circuit test (experiment #3). By performing

1.INTRODUCTION Most high-precision machines are positioning stages with Multiple degrees of freedom(DOF)‚ which often consist of cascaded long-and short-stroke linear actuators that are supported by mechanical or air bearings. Usually‚ the long stroke actuator has micrometer accuracy‚ while the Submicron accuracy is achieved by the short-stroke actuator. To build a high-precision machine‚ as much disturbances as possible should be eliminated. Common sources of disturbances are vibrations

Home Bulbs ECET105 FINAL PROJECT ASSIGNMENT 7-Jan-2014 2013-2014 Objectives: We are explaining in this project houses parallel connections for the lights (the bulbs). We choose this subject because parallel connection is the best for houses. We will mention the equipment and the procedure of the circuit so it could be clearer. Also the energy that comes out is a renewable energy system. Introduction/Theory: parallel circuit: a closed circuit in which the current divides into two
