A cluster of not-circles at a gate\'s inputs Which one of the following Boolean equations states that \"Q proves true only when every input value is true\"? A. Q = A + B + C B. Q = A middot B middot C C. Q = A B C D. Q = A times B times C The position value four places to the left in a binary number is A. decimal 1000. B. decimal 1111. C. decimal 4. D. decimal 8. Which of the following Boolean equations best describes a NOR function? A. Q = A middot B B. Q = A - B C. Q = A + B D. Q = A B Which one of the following Boolean equations states that Q is true when one - and only one-input is true. A. A = A + B + C B. Q = A middot B middot C C. A B C D. Q = A times B times C In a circuit where true is logic 0 and false is logic 1, the logic is said to be logic. A. positive B. negative C. three-state D. four-state Normally, in NEMA (National Electrical Manufacturers Association) logic schematics you would assume that input logic 1 A. Closes NO contacts and open NC contacts. B. Opens NO contacts and closes NC contacts. C. Closes both NO and NC contacts. D. Opens both NO and NC contacts.

Solution

6.Ans) B--4D2

Reason : 4D2 in hex converts decimal as follows-----4*16²+13*16+2*16⁰=1024+208+2=1234 decimal

-------------------------------------------------

7Ans) C-

digital logic involves only 2 states similary binary system involves two symbols 0 or 1,it best suits digital applications
