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






2. Are and Ohms






3. 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






4. Nano






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






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






7. 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.






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






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






10. Tera






11. Mega






12. Kilo






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






14. An electrical device used to store electrical charge.






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






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






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






18. Milli






19. 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.






20. 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.






21. Pico






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. Tera






24. 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






25. Pico






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






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






28. V or E and Volt (V)






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






30. Milli






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






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






33. Insulating board containing conductive tracks for circuit connections.






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






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