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






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






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






4. Giga






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






6. 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.






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






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






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






10. Nano






11. Kilo






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. C and Farad (F)

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






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






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






18. 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.






19. Mega






20. V or E and Volt (V)






21. C and Farad (F)






22. 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.






23. V or E and Volt (V)






24. An electrical device used to store electrical charge.






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






26. Mega






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






28. 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.






29. 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.






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






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






32. Giga






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






34. 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.






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






36. Insulating board containing conductive tracks for circuit connections.






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






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






39. 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.






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






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

44. 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.






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






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