EXP 1 - .STUDY OF MICROWAVE SYSTEM AND COMPONENTS AIM: To study the Microwave system and components. MICROWAVE SYSTEM: A Microwave system normally consists of Transmitter subsystems including a microwave oscillator wave guide and a terminating antenna and a receiver subsystem that includes a receiving antenna transmission line or wave guides‚ A microwave amplifier and a receiver . MICROWAVE SYSTEM:

telephone you own‚ there has to be some device that allows you to talk to and listen to. This device is called the handset. The handset is usually made out of plastic and inside it are two main components: the transmitter and the receiver. THE TRANSMITTER It is the job of the transmitter to turn the air pressure created by your sound waves to electrical signals so they can be sent to the other telephone. The waves hit a thin skin called the diaphragm that is physically connected to a reservoir

radar‚ which can automatically react to the operational environment to optimize performance. Conventional radars fall into two categories independent of what functions they perform. The first category has fixed antenna with centralized transmitters which produces patterns by reflector or passive array antennas. The beaming being fixed‚ scanning can only be achieved by physically moving the antenna. Typically a surveillance radar will produce a fan shaped beam with a fixed elevation illumination

Eventually he makes his way back to where the plane crashed and discovers a survival pack‚ .22 rifle‚ and a transmitter. He attempts to make a distress call with the transmitter but thinks it’s broken since he doesn’t know how to use it. A passing plane hears his distress call and rescues

Communications have changed the way we live and the way we kill. In World War II the Royal Corps of Signals (founded in 1920) duty was to operate and repair all army communications equipment. The radio transmitters of WWII served their intended purpose well‚ of a low frequency a low frequency transmitter and receiver‚ but the biggest problem was the weight factor of the battery pack needed to power these devices. So to offset the weight problem engineers went to lighter shorter lasting battery which

In 1876‚ Alexander Graham Bell invented the telephone. This invention was a small remodel of the first underwater telegraph. It has two parts: a transmitter and a receiver. The transmitter was composed of three parts: a drum-like device (a cylinder with a covered end)‚ a needle‚ and a battery. There was only one hole that one would speak into and listen out of. The telephone allows instant long-range communication

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. The transmission & reception of ultrasonic waves is

Brian is going to visit his father in Canada and is on a plane with him and a pilot. Brian Robeson‚ a thirteen-year-old kid from New York City. He is the main traveler on a little plane made a beeline for the oil fields of Canada. Brian is en route to go through the mid year with his dad‚ and he’s inclination completely mooched about his guardians’ late separation. Brian doesn’t have much time to harp on his miserable family circumstance‚ however‚ on the grounds that the pilot—the main other individual

1. INTRODUCTION The project “Automated Electricity Meter” aims to move away from the traditional method of manual reading of electricity meters in which an individual has to physically record the reading. Instead the project proposes to successfully be able to take the meter reading automatically without having a person be physically present while taking the reading‚ thereby reducing manpower requirement. This system helps the users by alerting them about the peak loads (max energy consumption)
