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.

34. A type of inductor used to block or choke off high frequencies






35. In addition (Oring) and multiplication (ANDing) of three or more variables - the order in which the variables are grouped makes no difference






36. The total number of data units(bits - nibbles - bytes - words) that a memory can store.






37. In a PLD - a matrix formed by rows of product- term lines columns of input lines with a programmable cell at each junctions. In VHDL - an array is an ordered set of individual items called elements with a single identifier name.






38. A type of PLD nonvolatile programmable link that can be left open or can be shorted once as directed by the program






39. An instrument that can specify each of the other instruments on the bus as either a talker or a listener for the purpose of data transfer.






40. A combination of logic gates interconnected to produce a specified Boolean function with no storage or memory capability; sometimes called combinatorial logic
