Introduction
The basic Frequency Modulation communications system has:
1) Transmitter, which is the sub-system that takes the information signal and processes it prior to transmission. The transmitter modulates the information onto a carrier signal and broadcasts it over the channel
2) Channel: The medium which transports the modulated signal to the receiver. In this project, LED will be connected to FM transmitter end. Signals then will be picked up by the Photo Detector diode right before the FM Receiver
3) ....etc

Abstract:
A stepper motor is an electromechanical device, which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the i ....etc

Asymmetrical Digital Subscriber Line

1.Links subscriber and internet service provider only for residential users.

2.Uses existing local loops.

3.Uses currently installed twisted pair cable.

4.Can carry broader spectrum of 1MHz or more.

ADSL CONFIGURATION

The twisted pair local loop is actually capable of handling bandwidths up to 1.1Mhz, but the filter installed at the end office of the telephone company where each local loop terminates limits the bandwidth to 4Khz(for voice comm.). If the filter is removed the entire 1.1Mhz i ....etc

In this paper a novel method for the space resolved dissection (molecular surgery) of DNA using electrostatic molecular manipulation is proposed and demonstrated. In conventional biochemistry DNA cutting enzymes and DNA are mixed in water, so the cutting reactions occur only by stochastic chances. In contrast, the present method is based upon a physical manipulation and enables the deterministic cutting of DNA at any position on a DNA molecule. In order to realize this space resolved cutting, the target DNA is stretched straight by electrostati ....etc

wireless power transmission is the process that takes place in any system where electrical energy is transmitted from a power source to an electrical load, without interconnecting wires. Wireless transmission is useful in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible.While the physics are identical, wireless energy transfer is slightly different from wireless transmission for the purpose of telecommunications (the transferring of information), such as radi ....etc

WITRICITY
ABSTRACT
The technology used for wireless power transmission is known as witricity. Wireless power transmission is not a new idea, Nikola Tesla proposed theories of wireless power transmission in the late 1800s and early 1900s. Tesla's work was impressive, but it did not immediately lead to wide spread practical methods for wireless power transmission. Since then many researchers have developed several techniques for moving electricity over long distances without wires. Some exist only as theori ....etc
