(X．Y)'=X'+Y'

(X+Y)'=X'Y'

EX1

F(X,Y,Z)=X'Y'Z+X'YZ'+XYZ+XY'Z

(Y'Z'+X'YZ+XZ’)'

=(Y+Z)(X+Y'+Z')(X'+Z)

EX2

F(W,X,Y,Z)=Σm(0,1,2,3,5,7,10)

簡化為和項之積

=(XZ'+WY'+WZ)'’

=(X'+Z)(W'+Y)(W'+Z')

EX3

Σm(0,2,4,6,8,10,13,15)

=(WXZ'+X'Z+W'Z)'

=(W'+X'+Z)(X+Z')(W+Z')

4/26 Output輸出

Output 輸出
-->Data that has been processed into a useful form called information
Display Devices 顯示器
-->Output device that visually conveys information
-->Information on display device sometimes called soft copy

CRT Monitor 螢幕
-->Contains cathode-ray tube
-->Screen coated with tiny dots (consists of a red,blue,and green)of phosphor(磷) material
resolution 解析度
-->Sharpness and clarity of image
Video card(graphics card) 顯示卡
-->converts digital output from computer into analog video signal

Flat-Panel Displays (LCD monitor液晶螢幕)
-->Uses liquid crystal display
-->Take up less desk space than CRT monitor

-->Uses liquid compound to present information on a display

Printer印表機

printer
-->Output device that produces text and graphics on paper
-->Result is hard copy,or printout
-->主要可以分成 "撞擊式印表機" 與 "非撞擊式印表機"

撞擊式印表機 (impact printer)
是藉由撞擊色帶、色帶來進行列印。
-->forms characters by striking mechanism against inked ribbon that contacts paper
點陣式印表機 dot-matrix printer
-->Impact printer that produces printed images when tiny wire pins strike ribbon
行列式印表機(line printer)來進行大量列印

非撞擊式印表機(nonimpact printer)
-->forms characters and graphics without striking paper
噴墨印表機(ink-jet printer)
-相機印表機(photo printer)
雷射印表機(laser printer)
-->Typically costs more than ink-jet printer,but is much faster
熱感應式印表機(thermal printer)
-->Generates images by pushing electrically heated pins against heat-sensitive paper
繪圖機 (plotter)
-->Large-format printer

Speakers and Headsets
audio output device
-->Computer component that produces music,speech,or other sounds
