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. Giga






3. 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/






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






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






6. P and Watt (W)






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






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. Insulating board containing conductive tracks for circuit connections.






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






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






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






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

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






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. 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/






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






19. An electrical device used to store electrical charge.






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






21. 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






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






23. 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.






24. 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.






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






26. Micro






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