analog (D/A) converters and applied to the picture-tube and audio circuits. The analog to digital (A/D) conversion, digital processing, and Digital to analog (D/A) conversion are all take place in the five digital ICs.This term paper are primarily the discussion of digital television system (block diagram), the basic principles in how to the conversion take place, the comparison of both analog television and digital television tackles in research and analysis section and the advantages tackles in finding section.BACKGROUND OF STUDYTo understand further the comparison of both digital and analog television and there advantage listed in finding section of this term paper. Let as first tackle the digital television system, this included parts of Analog to digital and digital to analog conversion and the basic digital conversion and storage concept.THE DIGITAL TELEVISION SYSTEM FIGURE 1 DIGITAL TELEVISION SYSTEM CRTFigure 1, show the digital television system which consist of image source or a image you want to capture, a means such as a camera of converting the image into analog electronic signal , a mean of transforming the analog signal into a digital signal ( analog to digital converter or A/D), some process(PD) which is applied to the digital signal, a means of re-transforming the resulting digital signal back to the analog domain (digital to analog converter or D/A) and means such as a display of reconverting the analog signal back into light for the benefit of the observer.The digital process varies according to the application. It can be a variable time delay used for frame synchronization and time base correction a video processor that correct for luminance and chrominance error, an image manipulator that permits digitally generated effects and graphics to be added to the image a data-compression scheme to reduce the amount of data or simply a transmission path.
