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. P and Watt (W)






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






3. 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.






4. Nano






5. 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.






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






7. P and Watt (W)






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






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






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






11. V or E and Volt (V)






12. 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/






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






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






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






16. 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.






17. Milli






18. Kilo






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






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






21. 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.






22. 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.






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






24. Giga






25. Tera






26. Micro






27. An electrical device used to store electrical charge.






28. Are and Ohms






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






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






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






32. 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.






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






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






35. 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.






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






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






38. 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.






39. Pico






40. 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






41. 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






42. Pico






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






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






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






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






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






48. 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.
