Dielectric Resonator
1.Introduction
A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field which redu ....etc

Lecture 3 Oscillator



Oscillators
Oscillation: an effect that repeatedly and regularly fluctuates about the mean value
Oscillator: circuit that produces oscillation
Characteristics: wave-shape, frequency, amplitude, distortion, stability

Application of Oscillators

Oscillators are used to generate signals, e.g.
Used as a local oscillator to transform the RF signals to IF signals in a receiver;
Used to generate RF carrier in a transmitter
Used to generate clocks in digital systems;
Used as s ....etc

METAL DETECTOR

ABSTRACT
In security aspects, metal detector isan essential equipment. But, the metal detector, which is available in the market today, is very costly. Hence this stands as a problem for hobbyists and for small applications. Hence we have taken an endeavor to bring out a metal detector of minimum cost.

RFID BASED SHOPPING TROLLEY
SYNOPSIS:
The objective of this project is to improve the speed of purchase by using RFID. This project is designed to use the RFID based security system application in the shopping trolley.
This project is used in shopping complex for purchase the products. In this project RFID card is used as security access for product. If the product is put in to the trolley means it will shows the amount and also the total amount. But in this project RFID card is used for accessing the products. So thi ....etc

Introduction

In digital communication , CellonicsTM offers a fundamental change to the way modem solutions have traditionally been designed and built. CellonicsTM technology introduces a simple and swift Carrier - Rate DecodingTM solution to the receiving and decoding of a modulated signal. It encodes and decodes signals at one symbol per cycle-a feature not found elsewhere. Its simplicity will obsolete the super heterodyne receiver design that has been in use since its invention by Major Edward Armstrong in 1918.In fact, according to one e ....etc

Experimental conguration for investigating the dynamics and the statistics
of the phase locking level of coupled lasers that have no common frequency
is presented. The results reveal that the probability distribution of the phase
locking level of such coupled lasers ts a Gumbel distribution that describes
the extreme value statistic of Gaussian processes. A simple model, based
on the spectral response of the coupled lasers, is also described, and the
calculated results are in good agreement with the experimental results.
Phase locking ....etc

ABSTRACT
In today's fast moving World, the accidents are increasing at a very fast rate. One of the major causes of these accidents is over a speeding of vehicles. A major step has been taken rather to increase the road safety, so as to minimize the accidents

One of a major development was the introduction of speed cameras. This camera, usually containing radar, is electronic devices those working are still a mystery to most electronic hobbyists. The principle of these speed cameras is Doppler Eff ....etc
