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. Consisting of numerals - letters - and other characters






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






3. To decrease the binary state of a counter by one






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






5. In addition (Oring) and multiplication (ANDing) of three or more variables - the order in which the variables are grouped makes no difference






6. The ability of a capacitor to store electrical charge.






7. A type of semiconductor memory that stores data in the form of charge packets and is serially accessed






8. A circuit that prevents loading of an input or output






9. A logic circuit used to add two binary numbers






10. The beginning address of a segment of memory






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






12. American Standard Code for Information Interchange; the most widely used alphanumeric code.






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






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






15. Arithmetic Logic Unit; the key processing element of a microprocessor that perfoms arithmetic and logic operations.






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






17. A combined coder and decoder






18. A type of IC package whose leads must pass through holes to the other side of a PC board






19. A type of counter in which each stage is clocked from the output of the preceding stage.






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






21. A connection at the midpoint of a winding in a transformer






22. American National Standards Institute






23. Basic input/output system; a set of programs in ROM that interfaces the I/) devices in a computer system






24. A relatively small - high- speed memory that stores the most recently used instructions or data from the larger but slower main memory






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






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






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






28. American wire gauge; a standardization based on wire diameter






29. In addition - the number to which the addend is added






30. 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.






31. A digital circuit device that converts coded information into another (familiar) or noncoded form






32. A bridge circuit that is in the balanced state as indicated by 0 V across the output.






33. The mathematics of logic circuits






34. The application of a dc voltage to an electronic device to produce a desired mode of operation






35. The process of producing an output carry in full- adder when both input bits are 1s.






36. A interconnection of electrical components designed to produce a desired result. A basic circuits consists of a source - a load and an interconnecting current path.






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






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






39. A reduction of the output signal compared to the input signal - resulting in a ratio with a value of less than 1 for the output voltage to the input voltage of a circuit.






40. A combination of logic gates interconnected to produce a specified Boolean function with no storage or memory capability; sometimes called combinatorial logic






41. The effect created when a signal is sampled at less than twice the signal frequency. Aliasing creates unwanted frequencies that interfere with the signal frequency.






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






43. Direct memory access; a method to directly interface a peripheral device to memory without using the CPU for control






44. One current path in a parallel circuit; a current path that connects two nodes






45. In a PLD - a matrix formed by rows of product- term lines columns of input lines with a programmable cell at each junctions. In VHDL - an array is an ordered set of individual items called elements with a single identifier name.






46. A class of integrated logic circuits that is implemented with a type of field effect transistor






47. Characterized by ten states or values






48. A one- way group of conductors from the to a memory - or other external device - on which the address code is sent






49. The opposition of a capacitor to permit current; the reciprocal of capacitive reactance. The unit is the siemens.






50. A digital counter having ten states
