When adding numbers in the 2's complement system, always carry the sign bit?
True or False
When adding numbers in the 2's complement system, always carry the sign bit? True or False
When subtracting two numbers, we also use the 2’s - complement system. The number to be subtracte d (the subtrahend) is changed to its 2’s - complement and then added to the minuend (the number the subtrahend is being subtracted from). Construct a circuit that performs this task. The input s of the circuit should be two four bit numbers of which the first bit is the sign bit and a control input which determines whether these number are added...
An 8-bit register contains 87h. If this computer represents the numbers in 2’s complement system, what negative number in decimal does these 8 bits represent? Please show your work step by step
Question 4 What's the result of adding the following two numbers in 2's complement system (Assume we're limited to 6-bits)? 101011 + 101010 1110101 110101 None of these Result is invalid because addition generates an overflow

convert -99 into 8-bit sign-magnitude, 1's complement, 2's complement. show detailed explanations for all conversions.
(5 points) Convert the following decimal numbers to 8-bit two's complement binary numbers and carry out the additions in binary. Indicate whether the sum overflows the 8-bit result. If not show the result as a decimal number. a) 39 + (-78) b) -43 + (-92)
convert -97 to 8-bit sign-magnitude, 1's complement, 2's complement and excess-127. Please be careful and explain all the steps and details.
For the following decimal numbers, convert to 8-bit binary numbers and perform addition. Use 2's complement signed numbers when subtraction is indicated. (a) 2710+ 3410 (b) 520-1810 (c) 3110 - 6310
1. If we had two 4-bit signed 2's complement numbers, X--4 and Y-6 and we wanted to compare them, we might calculate X-Y (a) Show that calculation (b) Explain how the result tells us that Y>IX (c) Now show the calculation for Y. X (d) Explain how this also shows us that Y>X 2. We talked about an ALU that takes two 4-bit inputs, A and B, and then generates a 4-bit result, S, based on a 2-bit command, F1FO....
Construct the 8-bit ripple-carry adder/subtractor for signed integers. Negative numbers are in the 2's complement form. The circuit has inputs X(7:0), Y(7:0), CO, M and outputs S(7:0), carry-out of MSB C8, OFL (OFL 1 when it occurs). The circuit should perform addition and subtraction of 8-bit signed numbers 2. with M-1 and M-0, respectively. a) Obtain the schematic for the 8-bit adder/subtractor with two 4-bit adder/subtractors from problem 1 as building blocks. X, Y, A, B, S can be shown...
