Digital Arithmetic Operations and Circuits Questions and Answers
Digital Arithmetic Operations and Circuits play an essential role in programming questions and answers related to computer architecture and electronics. This topic covers binary addition, subtraction, multiplication, division, and their implementation using combinational circuits like adders and multiplexers. Understanding these fundamentals helps candidates prepare for GATE, ISRO, and DRDO exams where logic design questions are common. Practicing digital electronics MCQs and circuit-based problems improves analytical skills and strengthens the foundation for embedded and VLSI design interviews.

21. The range of positive numbers when using an eight-bit two's-complement system is:
- 0 to 64
- 0 to 100
- 0 to 127
- 0 to 256
22. What are the two types of basic adder circuits?
- sum and carry
- half-adder and full-adder
- asynchronous and synchronous
- one- and two's-complement
23. A half-adder circuit would normally be used each time a carry input is required in an added circuit.
- TRUE
- FALSE
26. Determine the two's-complement of each binary number. 00110 00011 11101
- 11001 11100 00010
- 00111 00010 00010
- 00110 00011 11101
- 11010 11101 00011
27. Solve this binary problem: 01110010 – 01001000 =
- 00011010
- 00101010
- 01110010
- 00111100
28. What distinguishes the look-ahead-carry adder?
- It is slower than the ripple-carry adder.
- It is easier to implement logically than a full adder.
- It is faster than a ripple-carry adder.
- It requires advance knowledge of the final answer.
29. Half-adders can be combined to form a full-adder with no additional gates.
- TRUE
- FALSE
