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. Mega






2. V or E and Volt (V)






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






4. 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/






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






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






7. Insulating board containing conductive tracks for circuit connections.






8. Nano






9. V or E and Volt (V)






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






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






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






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






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






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






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

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






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






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






28. Are and Ohms






29. 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/






30. 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.






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






32. 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.

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






39. 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.






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






41. 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.
