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. Milli






2. A way of representing some physical quantity - such as temperature or velocity - by a proportional continuous voltage or current. An analog voltage or current can have any value within a defined range.






3. Kilo






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






5. Tera






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






7. 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.






8. 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.






9. Mega






10. An electrical device used to store electrical charge.






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






12. A two terminal device that conducts in only one direction.






13. 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.






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






15. C and Farad (F)






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






17. I and Ampere or Amp (A)






18. P and Watt (W)






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






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






21. Are and Ohms






22. Abbreviation of System International - a system of practical units based on the meter - kilogram - second - ampere - Kelvin - mole - and candela.






23. Abbreviation of System International - a system of practical units based on the meter - kilogram - second - ampere - Kelvin - mole - and candela.






24. 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/






25. The unwanted formation of a conductive path of solder between conductors.






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






27. Signal in the form of a rectangular pulse train or a square wave.






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






29. C and Farad (F)






30. The smallest particle of an element that still has the same characteristics as the element.






31. The process of applying a thin coat of solder to materials prior to their being soldered; for example - application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering the conductor.






32. A floating point system in which numbers are expressed as products consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three.






33. The unwanted formation of a conductive path of solder between conductors.






34. 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.






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






36. A way of representing some physical quantity - such as temperature or velocity - by a proportional continuous voltage or current. An analog voltage or current can have any value within a defined range.






37. Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.






38. Pico






39. 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.






40. Giga






41. Milli






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






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






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






45. Circuit that is capable of sensing and holding a signal until the event that changed the signal can be addressed.






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






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






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






49. Kilo






50. The process of applying a thin coat of solder to materials prior to their being soldered; for example - application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering the conductor.
