Digital Electronics Vocab

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 the produces a digital output signal that is half the frequency of the input.






2. P and Watt (W)






3. Numbers entered as a number from one to ten multiplied by a power of ten.






4. Term derived from 'transfer resistor.' Semiconductor device that can be used as an amplifier or as an electronic switch.






5. An IC package similar to a DIP - but smaller - which is designed for automatic placement and soldering on the surface of a circuit board.






6. Electronic test equipment that can perform multiple tasks. Typically one capable of measuring voltage - current - and resistance. More sophisticated modern digital multimeters also measure capacitance - inductance - current gain of transistors - and/






7. A group of flip-flops (typically 4 or 8) that are arranged so that the values stored in the flip-flops are shifted from one flip-flop to the next for every clock.






8. A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values.






9. F and Hertz (Hz) or Cycles per sec.






10. Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.






11. Insulating board containing conductive tracks for circuit connections.






12. Milli






13. Any material that allows the free movement of electric changes - such as electrons - to provide an electric current.






14. An electrical device used to store electrical charge.






15. Kilo






16. A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value.






17. Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them.






18. Milli






19. Pico






20. A series of logic 1s and 0s plotted as a function of time.






21. Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance.






22. A circuit board for wiring temporary circuits - usually used for prototypes or laboratory work.






23. A very common IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board.






24. Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance.






25. Metallic alloy of tin and lead that is used to join two metal surfaces.






26. C and Farad (F)






27. Tera






28. Nano






29. The instantaneous voltage of a waveform. Often used to mean maximum amplitude - or peak voltage - or a pulse.






30. Numbers entered as a number from one to ten multiplied by a power of ten.






31. A movement of electrical charges around a closed path or circuit.






32. V or E and Volt (V)






33. Are and Ohms






34. A solder connection that exhibits poor wetting and is characterized by a grayish - porous appearance due to excessive impurities in the solder - inadequate cleaning prior to soldering - and/or the insufficient application of heat during the soldering






35. Component made of material that opposes flow of current and therefore has some value of resistance.






36. Tera






37. Mega






38. The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential - which is in the opposite direction of electron flow.






39. Pico






40. F and Hertz (Hz) or Cycles per sec.






41. A group of flip-flops (typically 4 or 8) that are arranged so that the values stored in the flip-flops are shifted from one flip-flop to the next for every clock.






42. A square IC package with leads on all four sides designed for surface mounting on a circuit board.






43. Giga






44. A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values.






45. An electrical device used to store electrical charge.






46. Insulating board containing conductive tracks for circuit connections.






47. An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements - shaped like a figure-8 - which can be used to display decimal digits and other characters by turning on the appropriate elements.






48. V or E and Volt (V)






49. P and Watt (W)






50. Mega
