Performance Analysis of Phase Error Cancellation of PAL-D Television System Using Labview

Abstract

Television has been a part of our day to day life. So, sometimes we think how this system really works! In between Transmission and Reception, Information Signal passes through plenty of complex process and stages. We have Implemented, the process made on Chrominance signal (|C|) with the help of simulator, Lab VIEW 9, made by National Instruments in 1986. The Selection of appropriate camera is depending upon the three primary color of object. There are mainly three characteristic of chrominance signal. Hue, Saturation & Luminance. Amplitude of chrominance signal defines Saturation level and Phase angle of the signal determines Hue. So Chrominance circle, with magnitude level contains all colours of the world. Model describes the magnitude level and phase angle for the particular colour. Two colour difference signals are modulated in Quadrature Amplitude Modulation (QAM) manner. So by using this model you can show that how the QAM waves are looks like for particular colour. As well as the model describes how PAL-D System, used in the Asian country, works and how it is superior then the NTSC system used in American Country. Thus the concept of, Colour Television Transmission is designed in an oversimplified way.
