CRT MONITOR cathode-ray tube



Disadvantages of CRT

They have a big back and take up space on desk.
The electromagnetic fields emitted by CRT monitors constitute a health hazard to the functioning of living cells.
CRTs emit a small amount of X-ray band radiation which can result in a health hazard.
Constant refreshing of CRT monitors can result in headache.
CRTs operate at very high voltage which can overheat system or result in an implosion
Within a CRT a strong vacuum exists in it ....etc

Abstract:
This is one of great project based on AVR microcontroller. It use ATmega32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.
This project use C language and CODEVISION as compiler. So, it will be more easy to understand t ....etc

Introduction

The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the Braun tube. It was a cold-cathode diode, a modification of theCrookes tube with a phosphor-coated screen.

A cathode ray tube is a vacuum tube which consists of one or more electron guns, possibly internal electrostatic deflection plates, and a phosphor target. In television sets and computer monitors, the entire front area of the tube is scanned repetitive ....etc

More and more experimentsare now ‘PC-assisted.’ Alsoconventional acquisition systemsare very expensive. Since portablePCs are today common and a USB linkis a better solution than an old ISA bus,here we present an oscilloscope usingUSB port of the PC that operates at upto 10 kHz with ±16V input voltage. Ithas much more improved features thanthe PC-based oscilloscope and LEDscope for audio servicing published inEFY Dec. 2002 and Electronics ProjectsVol. 8, respectively. The oscilloscopeuses IC PIC18F2550 from Microchipas the main controller ....etc
