NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined

When Gandhi was 16 his father became very ill. Being very devoted to his parents‚ he attended to his father at all times during his illness. However‚ one night‚ Gandhi’s uncle came to relieve Gandhi for a while. He retired to his bedroom where carnal desires overcame him and he made love to his wife. Shortly afterward a servant came to report that Gandhi’s father had just died. Gandhi felt tremendous guilt and never could forgive himself. He came to refer to this event as "double shame." The incident

Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not until Max Planck‚ at the turn of the century‚ was a single mathematical formula for the observed distribution of the energy among

A radio wave is a type of electromagnetic wave. Radio waves have the longest wavelength(distance between successive crests of a wave) out of all of the types of electromagnetic waves known. Other properties of electromagnetic waves that are significant to Marconi’s discovery is that they can travel through empty space and travel at the speed of light. He combined this knowledge of radio waves and electromagnetic waves to create his wireless radio.(Radio Waves) Marconi

INTRODUCTION Electromagnetic compatibility (EMC) has been around since the early 1950s‚ predominantly regarding the motorised noise conducted over the power lines to sensitive equipments. [1] With the advancement of digital circuits‚ the switching speeds of equipments have increased dramatically. Since electromagnetic interference is caused by the changes in current with respect to

microwave. Introduction Thin Film Interference When plane electromagnetic wave of wavelength λ is incident on a dielectric surface‚ part of the electromagnetic wave is reflected‚ and part of it is transmitted. If the dielectric is thin‚ i.e. its thickness t is comparable to λ‚ the plane electromagnetic wave will be reflected again at the second dielectric surface‚ as shown in Figure 1. [pic] Figure 1. Electromagnetic waves incident at angle θ1 reflected from the top and bottom surfaces

How a Microwave Works By Zach Betten [pic] What is a Microwave? A microwave oven or microwave is a kitchen appliance that cooks or heats food by using electromagnetic waves. This happens by using microwave radiation to heat materials such as water and other things within the food. This leads to food being more evenly heated throughout. Basic microwave ovens heat food quickly and efficiently. One setback is that they do not brown or bake food in
