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 application program in development software packages that controls the design flow process and translates source code into object code in a format that can be logically tested or downloaded to a target device






2. The interval of time occupied by a single bit in a sequence of bits; the period of the clock






3. The current left after the total load current is subtracted from the total current into the circuit






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






5. In a division operation the quantity that is being divided






6. The average of a sine wave over one half- cycle. It is 0.637 times the peak value.






7. 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.






8. Information in numeric - alphabetic - or other form.






9. Describes a number system with a base of ten






10. To connect 'end- to- end' as when several counters are connected from the terminal count output of one counter to the enable input of the next counter






11. A electrical property of matter that exist because of an excess or a deficiency of electrons. Can be either positive or negative






12. Dynamic random- access memory; a type of semiconductor memory that uses capacitors as the storage elements and is a volatile - read/write memory






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






14. The location of a given storage cell or group of cells in a memory; a unique memory location containing on byte






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






16. A circuit (digital service) that switches digital data from one input line to several output lines in a specified time sequence






17. Stands for Complementary Metal-Oxide Semiconductor and is implemented with a type of field transistor






18. A combined coder and decoder






19. The process that prevents two sources from using a bus at the same time






20. Voltage Divider Rule in determining TEC Thevenin Equivalence Circuit






21. The time from the application of a valid memory address to the appearance of valid output data






22. Dual in - line memory module






23. A receiving device on a bus






24. A complex programmable logic device that consists basically of muliple SPLD arrays with programmable interconnections.






25. A method for internally testing a PLD based on the JTAG standard (IEEE std.)






26. The portion of the CPU that interfaces with the system buses and fetches instructions - reads operands - and writes results.






27. A method for the automated testing of printed circuit boards in which the board is mounted on a fixture that resembles a bed of nails that makes contact with test points






28. A binary digit - which can be either 1 or 0






29. A programming language that uses English like words and has a one- to- one correspondence to machine language






30. Having two stable states. Flip- flops and latches are bistable multivibrators.
