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. An energy source that uses a chemical reaction to convert chemical energy into electrical energy.






2. An electrical device consisting of two conductive plates separated by an insulating material and possessing the property of capacitance.






3. 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






4. The process of converting an analog signal to digital form






5. An instrument that can specify each of the other instruments on the bus as either a talker or a listener for the purpose of data transfer.






6. The smallest particle of an element possessing the unique characteristics of that element.






7. The total number of data units(bits - nibbles - bytes - words) that a memory can store.






8. An array of AND gates consisting of a matrix of programmable interconnection






9. The law that states ORing several variables and then ANDing the single variable with each of the several variables and the ORing the product






10. A combined coder and decoder






11. Altera HDL; a nonstandard HDL






12. An arrangement of electrical and/or electronic components interconnected in such a way as to perform a specified function






13. An electrical instrument used to measure current






14. A notational system for logic symbols that specifies input and output relationships thus fully defining a given function
