소개글
2017학년도 1학기 전기전자응용실험을 수강하면서 작성한 레포트들입니다. 디지털 마지막 프로젝트 실험입니다.예비레포트+결과레포트로 구성되어있으며, 성적은 A+를 받았습니다.
처음 실험하시는 분들에게 참고용으로 좋을 것 같습니다.

1-1. Theory
VGA(Video Graphics Array) is used in computer. It has 17 display modes, 256 colors by combination of RGB and represent 640480 of resolution. The principle of VGA's concept is as follows. First, hard disk's data is loaded into the RAM. Second, informations are calculated in CPU. Third, CPU send these information to graphic card. The last, VGA display these information to screen by combination of RGB.
[Figure. 1] shows the concept of this VGA. It consist of 15 pins. 1pin-RED, 2pin-GREEN, 3pin-BLUE, 13pin-Hsync, 14pin-Vsync, etc. VGA does digital process and DAC process. We can see the analog signals by these process. To understand VGA, knowing about VGA sync signal is very important.
VGA has two synchronization signals. There are Hsync signal and Vsync signal. [Figure. 2] shows the concept of this VGA Sync signal. HSync is for horizontal synchronization of VGA. And Vsync is for vertical synchronization of VGA.
