Q3:
What is wrong, if anything, with the circuit in the given figure based on the logic analyzer display accompanying the circuit?

A The CO terminal is shorted to ground.

B The S1 output is shorted to Vcc.

C The P1 input is not being added into the total.

D Nothing is wrong; the circuit is functioning correctly.

Q4:
Which of the statements below best describes the given figure?

A Full-carry adder; Sum = 1, Carry = 0

B Half-carry adder; Sum = 1, Carry = 0

C Half-carry adder; Sum = 0, Carry = 1

D Full-carry adder; Sum = 1, Carry = 1

Q5: An 8-bit register may provide storage for two's-complement codes within which decimal range?

A +127 to –127

B +128 to –128

C –128 to +127

D +128 to –127

Q6: A full-adder adds ________.

A two 4-bit binary numbers

B two 2-bit binary numbers

C two 2-bit numbers and one carry bit

D two single bits and one carry bit

Q7: The carry propagation delay in 4-bit full-adder circuits:

A is cumulative for each stage and limits the speed at which arithmetic operations are performed

B increases in direct ratio to the total number of full-adder stages, but is not a factor in limiting the speed of arithmetic operations

C is normally not a consideration because the delays are usually in the nanosecond range

D decreases in direct ratio to the total number of full-adder stages

Q8: An input to the mode pin of an arithmetic/logic unit (ALU) determines if the function will be:

A arithmetic or logic

B one's-complemented

C positive or negative

D with or without carry

Q9: Could the sum output of a full-adder be used as a two-bit parity generator?

A Yes

B No

Q10: In VHDL, what is a GENERATE statement?

A The start statement of a program

B Not used in VHDL or ADHL

C A way to get the computer to generate a program from a circuit diagram
