LECTURER NAME : MISS NORHATINIGROUP NAME : AHMAD MUSTAQIM SYAHMIE BIN KAMARUDDINMUHAMMAD RAIMI BIN ROZAINORDIGITAL ELECTRONICS FUNDAMENTALAND GATEINTRODUCTION:An AND GATE consists of two inputs (known as A and B) and one output (known as X)An AND GATE acts like two switches A and B in seies! Onl" when #oth switches A and B ae closed the #ul# X will #e tuned on!Also known as $All or Nothing% &ateAND &ate cicuit usin& switchesABXAND gate symbolAND &ate will onl" poduce output hi&h (') when all the input ae hi&h (')( else the output ae low ())!
