Digital Fundamentals

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.

20. An arrangement of electrical and/or electronic components interconnected in such a way as to perform a specified function






21. A logic gate that produces a High output only when all of the inputs are HIGH






22. The opposition of a capacitor to permit current; the reciprocal of capacitive reactance. The unit is the siemens.






23. One current path in a parallel circuit; a current path that connects two nodes






24. An electrical instrument used to measure current






25. A type of bistable multivibrator in which the output assumes the state of the D input on the triggering edge of a clock pulse.

27. Having two directions. the stored data can be shifted right or left






28. The rotational rate of a phasor which is related to the frequency of the sine wave that the phasor represents






29. A interconnection of electrical components designed to produce a desired result. A basic circuits consists of a source - a load and an interconnecting current path.






30. A two terminal circuit containing voltage sources - current sources - and resistors can be modeled as a voltage source in series with a resistor






31. In relation to VHDL feature that permits operations to be processed in a parallel;that is operations that occur simultaneously






32. The application of a dc voltage to an electronic device to produce a desired mode of operation






33. The portion within the microprocessor that provides the timing and control signals for getting data into and out of the microprocessor and for synchronizing the execution of instructions.
