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. 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






2. A document that specifies parameter values and operating conditions for an integrated circuits or other device






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






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






5. 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






6. Having two stable states. Flip- flops and latches are bistable multivibrators.






7. A connection at the midpoint of a winding in a transformer






8. A programming language that uses English like words and has a one- to- one correspondence to machine language






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

13. A combined coder and decoder






14. Characterized by ten states or values






15. A set of interconnections that interface one or more devices based on a standardized specification






16. The inverse of opposite of a number - in Boolean algebra - the inverse function - expressed with a bar over the variable. The complement of a 1 is a 0 - and vice versa






17. The unit of electrical current






18. A reduction of the output signal compared to the input signal - resulting in a ratio with a value of less than 1 for the output voltage to the input voltage of a circuit.






19. Data Communications equipment






20. The smallest particle of an element possessing the unique characteristics of that element.






21. The time from the application of a valid memory address to the appearance of valid output data






22. 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.






23. A digital circuit that compares the magnitudes of two quantiities and produces an output indicating the relationship of the quantities






24. A combination of input literals that cannot occur and can be used as a 1 or 0 on a Karnaugh Map for simplification

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






26. 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.






27. Digital audio tape; a type of magnetic tape format






28. 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






29. Digital Signal Processor; a special type of microprocessor that processes data in real time






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






31. The actual current in a branch






32. The mathematics of logic circuits

35. The ability of a capacitor to store electrical charge.






36. A series of bits describing a final design that is sent to the target device during programming






37. A logic circuit used to add two binary numbers






38. 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






39. A circuit that prevents loading of an input or output






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






41. A complex programmable logic device that consists basically of muliple SPLD arrays with programmable interconnections.






42. To connect 'end- to- end' as when several counters are connected from the terminal count output of one counter to the enable input of the next counter






43. Direct memory access; a method to directly interface a peripheral device to memory without using the CPU for control






44. The VHDL unit that describes the internal operation of a logic function; the internal functional arrangement of the elements that give a device its particular operating characteristics.






45. The process of converting an analog signal to digital form






46. In addition - the number that is added to another number called the augend






47. The interval of time occupied by a single bit in a sequence of bits; the period of the clock
