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






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






3. Insulating board containing conductive tracks for circuit connections.






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






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






6. Are and Ohms






7. 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.






8. Pico






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






10. Tera






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






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






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






14. Kilo






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






16. Milli






17. An electrical device used to store electrical charge.






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






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






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






21. Kilo






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






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






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






25. 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.






26. C and Farad (F)






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






28. Giga






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






30. I and Ampere or Amp (A)






31. 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/






32. 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.






33. 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.






34. An electrical device used to store electrical charge.






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






36. 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.






37. Milli






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






39. 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.






40. 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/






41. Giga






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






43. V or E and Volt (V)






44. 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.






45. 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






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






47. Mega






48. 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.






49. 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.






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