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. C and Farad (F)






2. V or E and Volt (V)






3. Tera






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






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






6. Milli






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






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






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






10. 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.






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






12. Nano






13. 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.






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






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






16. An electrical device used to store electrical charge.






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






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






19. Micro






20. Micro






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






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






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






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






26. Milli






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






28. Are and Ohms






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






30. 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.






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






32. C and Farad (F)






33. 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/






34. 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.






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






36. Kilo






37. Mega






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






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






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






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






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






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






44. Insulating board containing conductive tracks for circuit connections.






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