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.
1. A one- way group of conductors from the to a memory - or other external device - on which the address code is sent






2. American Standard Code for Information Interchange; the most widely used alphanumeric code.






3. Sum of all the voltage drops in series equals to the source voltage

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






14. In Boolean algebra - the OR operation






15. Having two values or states; describes a number system that has a base of two and utilizes 1 and 0 as its digits






16. The basic timing signal in a digital system; a periodic waveform in which the interval between pulses equals the time for one bit; the triggering input of a flip- flop






17. A measure of the ability of a reactive circuit to permit current; the reciprocal of impedance. the unit is the siemens






18. A stage of the DSP pipeline operation in which instructions are assigned to functional units and are decoded.






19. The actual current in a branch






20. The phasor combination of resistive power (true power) and reactive power. The unit is the volt- amperes (VA).






21. The process of rippling an input carry to become the output carry in a full- adder when either or both of the input bits are 1's and the input carry is a 1






22. A combined coder and decoder






23. A method for internally testing a PLD based on the JTAG standard (IEEE std.)






24. Bipolar junction transistor; a semiconductor device used for switching or amplification. A BJT has two junctions - the base- emitter junction and the base- collector junction






25. Having two opposites charge carriers within the transistor structure






26. In a pulse waveform - the height or maximum value of the pulse as measured from its low level.






27. Altera HDL; a nonstandard HDL






28. An array of AND gates consisting of a matrix of programmable interconnection






29. A relatively small - high- speed memory that stores the most recently used instructions or data from the larger but slower main memory






30. The law that states ORing several variables and then ANDing the single variable with each of the several variables and the ORing the product






31. An asynchronous input used to reset a flip- flop (make the Q output 0); to place a register or counter in the state in which it contains all 0's






32. Information in numeric - alphabetic - or other form.






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






34. A program that translates an assembly language program for one type of microprocessor to an assembly language for another type of microprocessor






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






36. The portion of the CPU that interfaces with the system buses and fetches instructions - reads operands - and writes results.






37. An electrical instrument used to measure current






38. The number of protons in a nucleus
