not bounce off the ground it does not create as much static as AM does. Radio waves‚ which travel at the speed of light‚ cannot be seen‚ heard‚ or felt in any way. When you listen to the radio‚ contrary to what some think‚ you are hearing the receivers pick up the waves and turn them into sound. Three more types of radio waves are; ground waves‚ ionospheric waves and tropospheric waves. Ground waves travel from the antenna along the surface of the earth. Ionospheric waves‚ otherwise known

be used to communicate a more accurate signal. For this task‚ an audio information source (CD player) produces a signal that is converted to digital information. This information will then be sent to a receiver using laser light switching on and off to communicate zero’s and one’s. The receiver will pick up the laser light and convert the digital information back into an analogue signal for output to a speaker. See Figure 1 for a system block diagram.

light. He combined this knowledge of radio waves and electromagnetic waves to create his wireless radio.(Radio Waves) Marconi built his first radio with‚ of course‚ a transmitter and a receiver. Influenced by Hertz’s experiments‚ Marconi created an electrical circuit in which radio waves were produced. He used a coherer in the receiver to pick up radio signals and later added wire antennas to improve it. A coherer is a glass tube with loosely packed metal particles inside of it used to pick up radio

Pilot trolley method for trains AIM: To design a auto pilot trolley method for trains. Base Technology: EMBEDDED Abstract: It is a very useful project. By using this we can reduce the more train accident. The trolley is communicating with the train using ISM based RF signal. 432.92 MHz frequency signal is used for communication. As we do the project we use this frequency. It will sense the object using the IR signal‚ bomb is detected using metal detector‚ track open is sensed using limit

AMPLIFIER An amplifier is an electronic device increases the amplitude of a small signal to a useful level‚ even maintaining small signal’s detail. This is known as Linearity. FIGURES OF MERIT 1) Gain: Ratio between the magnitude of output and input signals. 2) Bandwidth: The Width of the useful frequency range. 3) Efficiency: The ratio between the power of the output and total power consumption. 4) Linearity: The degree of proportionality between input and output. 5) Noise: A measure of undesired

ultrasonic waves to measure the distance in between two points. The basic principal is based on the speed of ultrasonic waves in open air. We have used a microcontroller AT89S51 to transmit and receive ultrasonic waves through 40 KHz ultrasonic receiver and transmitters. By measuring the time required to travel the unknown distance by ultrasonic waves in air we can find out the distance between two points. The distance measured is displayed on a LCD display.
