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 circuit with a complete current path






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






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






4. A type of magnetic tape format






5. The normal level of a pulse waveform; the voltage level in the absence of a pulse.






6. The process or sequence of operations carried out to program a target device






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






8. One of the three regions in a bipolar Junction transistor(North junction of NpN)






9. A transformer in which the primary and secondary are in a single winding






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






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






12. A bidirectional set of conductive paths on which data or instruction codes are transferred into a microprocessor or on which the result of an operation is sent out from the microprocessor






13. Voltage Divider Rule in determining TEC Thevenin Equivalence Circuit






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






15. A nominally continuous electrical signal that varies in amplitude or frequency in response to changes in sound - light - heat - position - or pressure.






16. Transistor-Transistor Logic and is implemented with bipolar junction transistors






17. Describes a number system with a base of ten






18. A set of conductive paths hat connects the CPU to other parts of the computer to coordinate its operations and to communicate with external devices






19. The mathematics of logic circuits






20. A combined coder and decoder






21. 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.






22. A semiconductor device that conducts current in only one direction






23. The ratio of pulse width to period expressed as a percentage






24. Characteristic of cells in a Karnaugh map in which there is a single- variable change from one cell to another cell next to it on any of its four sides






25. Bipolar junction transistor; a semiconductor device used for switching or amplification. A BJT has two junctions - the base- emitter junction and the base- collector junction






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






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






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






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






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






31. A stage of the DSP pipeline operation in which instructions are assigned to functional units and are decoded.






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






33. The number of protons in a nucleus






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






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






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






37. Digital Signal Processor; a special type of microprocessor that processes data in real time






38. In addition - the number that is added to another number called the augend






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






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






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






42. 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






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






44. A program that translates an assembly language program for one type of microprocessor to an assembly language for another type of microprocessor






45. A unit of the cross - sectional area of a wire.






46. The rotational rate of a phasor which is related to the frequency of the sine wave that the phasor represents






47. A theorem that states that any amount of voltage sources and current sources can be combined into a single current source with a parallel resistor.
