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.

26. A basic logic operation in which a true(high) output occurs only when all the input conditions are true (high)






27. The range of frequencies for which the current (or output voltage) is equal to or greater than 70.7% of its value at the resonant frequency that is considered to be passed by a filter.






28. A filter that rejects a range of frequencies lying between two critical frequencies and passes frequencies above and below that range.






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






30. Characteristic of cells in a Karnaugh map in which there is a single- variable change from one cell to another cell next to it on any of its four sides
