What is Cathode Ray oscilloscope ?
In studying the various electronic, electrical networks and systems, signals which are functions of time, are often encountered. Such signals may be periodic or non-periodic in nature. The device which…
Cathode Ray Tube (CRT)
The cathode ray Tube (CRT) is the heart of the C.R.O. the CRT generates the electron beam, accelerates the beam, deflects the beam and also has a screen where beam…
Electron Gun of Cathode Ray Tube
This post is the continuation of the previous post on cathode ray tube. The electron gun section of the cathode ray tube provides a sharply focused electron beam directed towards the…
CRT Fluorescent Screen
The light produced by the screen does not disappear immediately when bombardment by electron ceases, i.e., when the signal becomes zero. The time period for which the trace remains on…
Time Base Generator
It has been mentioned earlier that the time domain oscilloscopes require a sweep generator that is linear with time for the x-axis display. The motion of spot on the screen…
Cathode Ray Tube Deflection System
This Post Deflection system of CRT is a continuation of my previous post Electron Gun of CRT. This post completely covers the Deflection system of the CRT. When the electron beam is…
Turbidity Analyzer Working Principle
Turbidity is an optical property of water based on the amount of light scattered and absorped by collodial and suspended particles. The turbidity value measured in FNU, FTU, NTU etc.…
