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






2. A code within DOS that allows various operations on files and includes a primitive assembler; to eliminate a problem in hardware or software.

13. 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






14. The portion within the microprocessor that provides the timing and control signals for getting data into and out of the microprocessor and for synchronizing the execution of instructions.






15. The basic timing signal in a digital system; a periodic waveform in which the interval between pulses equals the time for one bit; the triggering input of a flip- flop






16. The VHDL unit that describes the internal operation of a logic function; the internal functional arrangement of the elements that give a device its particular operating characteristics.






17. Dual in - line memory module






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






19. In relation to VHDL feature that permits operations to be processed in a parallel;that is operations that occur simultaneously






20. A type of semiconductor memory having capacitive storage cells that lose stored data over a period of time and therefore must be refreshed.






21. Having two opposites charge carriers within the transistor structure






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






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






24. A software compiler language for SPLD programming; a type of hardware description language (HDL)






25. A combination of input literals that cannot occur and can be used as a 1 or 0 on a Karnaugh Map for simplification

37. The main part of a computer responsible for control and processing of data; the core of a DSP that processes the program instructions






38. Digital audio tape; a type of magnetic tape format






39. A circuit that selects data from several inputs one at a time in a sequence and places them on the output; also called a multiplexer.






40. 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.






41. An adverse condition that could occur if two or more devices try to communicate at the same time on a bus
