  • Perfect Sine Waves At Particular Frequencies
    1,400 words
    Sam it PabuwalJeff ToplakEE 315 FUNCTION GENERATOR 12/12/20011. Abstract This project requires us to design and build a circuit that generates specified functions on the oscilloscope, as given on the project description. Also, we were required to design a means of selecting different frequencies and different amplitudes. This was especially difficult because the selection had to be made directly from the breadboard. For the final part of the lab, we were to draw the graphs we obtained to show ho...
  • Short Wave Radio Range
    833 words
    Electromagnetic radiation is defined as the emission and transmission of energy in the form of electromagnetic waves. An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves of sound, which scientists have categorized in order to depict the usefulness of the different properties. Theoretically, electromagnetic waves can be as lo...
  • Tuned Radio Frequency Receiver

    Radio: A Form of CommunicationPhysicsIdoh GerstenMr. ZambiziPhysicsMarch 12, 1995 Radio is a form of communication in which intelligence is transmitted without wires from one point to another by means of electromagnetic waves. Early forms of communication over great distances were the telephone and the telegraph. They required wires between the sender and receiver. Radio, on the other hand, requires no such physical connection. It relies on the radiation of energy from transmitting antenna in th...
  • Changing The Frequency Of The Wave
    668 words
    Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure / Planning Procedure: 1. Three students would g...
  • Pulses Of Compressed Air Of Sound Waves
    770 words
    Resonance and Sound... Physics and Music Since sound is the medium of music, most of the physics of music is the physics of sound. It's important to remember that sound waves are compression waves. You can imitate a compression wave by stretching out a slinky (you do have a slinky, don't you?) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope. Take a tuning fork (you do have a tuning fork, don't...
  • Effect On Radio Wave Propagation
    2,604 words
    Propagation as defined by Webster Dictionary as "the phenomenon of radio frequency energy traveling through the earth's atmosphere, as well as through the empty space above the atmosphere". Once radio-frequency energy has been emitted from an antenna it will travel away from the antenna, where it is generated from, at the speed of light. Once it is sent the wave exists and propagates independently of the system that produces it. This means that changes, which occur at the transmitter (antenna), ...
  • Sound Waves With A Given Frequency
    504 words
    Resonance RESONANCE: ' The property whereby any vibratory system responds with maximum amplitude to an applied force having the a frequency equal to its own. ' In english, this means that any solid object that is struck with a sound wave of equal sound wave vibrations will amplitude the given tone. This would explain the reason why some singers are able to break wine glasses with their voice. The vibrations build up enough to shatter the glass. This is called RESONANCE. Resonance can be observed...
  • Air Column The Phase Of A Wave
    1,123 words
    INTERNATIONAL BACCALAUREATE SUBSIDIARY LEVEL WAVES SUMMARY 4.1 Travelling wave characteristics A medium is a material through which a wave passes. When a wave passes, each part of the medium moves away from its normal position and then returns. This is called an oscillation. Oscillations within the medium are slight movements either side of the normal position. The wave motion is the disturbance that passes through the medium. A wave pulse causes the medium to have one oscillation. A continuous ...
  • Frequency Of The Carrier Wave
    882 words
    Radio Waves In the modern society, radio is the most widely used medium of broadcasting and electronic communication: it plays a major role in many areas such as public safety, industrial manufacturing, processing, agriculture, transportation, entertainment, national defense, space travel, overseas communication, news reporting and weather forecasting. In radio broadcasts, they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude m...
  • Continuous Wave Radar And Pulse Radar
    993 words
    Radar: A Silent Eye in the Sky Daniel Brook Period Two Today's society relies heavily on an invention taken for granted: radar. Just about everybody uses radar, whether they realize it or not. Tens of thousands of lives rely on the precision and speed of radar to guide their plane through the skies unscathed. Others just use it when they turn on the morning news to check the weather forecast. While radar seems to be an important part of our everyday lives, it has not been around for long. It was...
  • Radio Waves From An Antenna
    764 words
    Before beginning our research on radio waves, to us, radio waves were just waves going through the atmosphere, carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves, and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves, which represent voice and other soun...
  • Fourier Analysis
    631 words
    Fourier analysis of spatial and temporal visual stimuli has become common in the last 35 years. For many people interested in vision but not trained in mathematics this causes some confusion. The use of these Fourier methods does not mean that the visual system performs a Fourier analysis. At present it should be understood that this approach is a convenient way to analyze visual stimuli. Jean Baptiste Fourier, a mathematician, showed that any repetitive waveform can be broken down into a series...
  • Modulated And An Analogue Wave
    685 words
    The world around us in a standard sense such as conversation and listening is analogue - the basic principals of audio its self is a sound wave and wave forms donate an analogue signal. But with regards to modern society and its computers - we have to conform to their language - this is called binary logic, or a digital signal a series of 1's and 0's that get sequenced in code form. We generally refer to a digital signal as having a bit rate, this means that a signal holds 8 1's and 0's for ever...

    Jargon buster 2 G 2 G, the second generation or GSM, is the technology currently used in the operation of mobile phones. 3 G 3 G, or third generation, is the generic term used for the next generation of mobile communications systems. The new systems will enhance the services available today and offer multimedia and internet access and the ability to view video footage. The third generation technology used in the UK is called UMTS. These services operate at 2200 MHz. (2.2 GHz). Aerial / Antenna A...
