Digital Fundamentals

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A electrical property of matter that exist because of an excess or a deficiency of electrons. Can be either positive or negative






2. A type of inductor used to block or choke off high frequencies

11. A logic gate that produces a High output only when all of the inputs are HIGH






12. A resettable protective device used for interrupting execessive current in an electric circuit






13. A filter that passes a range of frequencies lying between two critical freqencies and rejects frequencies above and below that range.






14. The process of rippling an input carry to become the output carry in a full- adder when either or both of the input bits are 1's and the input carry is a 1






15. A group of eight bits






16. Sum of all currents entering a node is equal to the sum of all currents leaving the same node
