CO OZNACZA SŁOWO COMPARATOR
Komparator
W elektronice komparator jest urządzeniem, które porównuje dwa napięcia lub prądy i wysyła sygnał cyfrowy wskazujący, który jest większy. Posiada dwa analogowe zaciski wejściowe i jedno binarne wyjście cyfrowe. Wyjście jest idealnie Komparator składa się z wyspecjalizowanego wzmacniacza różnicowego o wysokiej wartości wzmocnienia. Są powszechnie stosowane w urządzeniach, które mierzą i digitalizują sygnały analogowe, takie jak konwertery analogowo-cyfrowe, a także oscylatory relaksacyjne.
Definicja słowa comparator w słowniku
Definicją komparatora w słowniku jest dowolny instrument służący do pomiaru właściwości systemu poprzez porównanie go ze standardowym systemem. Inną definicją komparatora jest obwód elektryczny, który porównuje dwa sygnały i wskazuje na stopień ich odmienności.

For the inverting comparator circuit, find values for the component resistors to
achieve VHtoL = .8VDD and VLtoH = .2VDD. Solution: VHtoL = VDDR1R1+R2//
Rf = .8VDD.Thus, R1=.8(R1+R2//Rf). Rearranging, we get R1=4(R2//Rf).
