In the given circuit, 7483 are additions and 7485 comparisons. Four-bit X and Y numbers are applied to the inputs of the circuit. In what situations would the output Q of this circuit be logic 1? A X+Y<8 ise B X+Y<7 ise C X+Y>7 ise D X+Y=8 ise E X+Y>4 ise

Please try typing format please

I need expert solution with circuit drawing

1. Consider the following two logic circuits. VDD A-6 B-d6 A-6 B-6 -6 -6 F VDD F t t A Circuit A Circuit B a. Do these two circuits implement the same logic function? If yes, what is that logic function? If no, give Boolean expressions for both circuits. b. Will these two circuits' output resistances always be equal to each other? c. Will these two circuits' rise and fall times always be equal to each other? Why or why not?

This question is from my digital system class, i hope you can help me so i can study

Electrical engineering need to design the following a room with four door, one lamp, the lamp will turned on ( logic one) if a one door is opened, or three doors is opened Otherwise the lamp turned off ( logic zero)

2. Explain which of the following instructions are invalid? State the invalidation reason and give the correct form for invalid instructions: a. MOV DL,AX b. MOV ES,CX c. MOV [BX],[2000] d. MOV BX,[AX] e. MOV CL,[BL+200] f. MOV 1234,DX g. MOV CH,[BX+SI+300] h. MOV DS,[SI+DI-5] i. MOV [4500],1234 j. MOV 200,[300]

What does a ASTABLE circuit do? How could these ideas be applied?

For the function f = w'2w'3 + w1w2 Work the problem with a 4-1 multiplexer and with a 2-1 multiplexer. With the 2-1 multiplexer implementation you can choose a select input (say w1) and try to express the output f in terms of the data inputs (w2 and w3).
