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 number of protons in a nucleus






2. 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.






3. In Boolean algebra - the OR operation






4. In addition - the number to which the addend is added






5. 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.






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






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






8. A notational system for logic symbols that specifies input and output relationships thus fully defining a given function






9. Having two opposites charge carriers within the transistor structure






10. A software compiler language for SPLD programming; a type of hardware description language (HDL)






11. The average of a sine wave over one half- cycle. It is 0.637 times the peak value.






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






13. 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.






14. A group of eight bits






15. 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






16. A condition where all the load currents are equal and the neutral current is zero






17. Arithmetic Logic Unit; the key processing element of a microprocessor that perfoms arithmetic and logic operations.






18. Transistor-Transistor Logic and is implemented with bipolar junction transistors






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






20. The ratio of pulse width to period expressed as a percentage






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

23. The digit generated when the sum of two binary digits exceeds 1






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






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






26. A semiconductor device that conducts current in only one direction






27. 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






28. Having no stable state. An astable multivibrator oscillates between two quasi- stable states.

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






31. The beginning address of a segment of memory






32. A number given in ampere- hours determined by multiplying the current times the length of the time (h) a battery can deliver that current to a load






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






34. A set of conductive paths hat connects the CPU to other parts of the computer to coordinate its operations and to communicate with external devices






35. A electrical property of matter that exist because of an excess or a deficiency of electrons. Can be either positive or negative






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






37. Burst extended data output dynamic random- access memory






38. A nominally continuous electrical signal that varies in amplitude or frequency in response to changes in sound - light - heat - position - or pressure.






39. An application program in development software packages that controls the design flow process and translates source code into object code in a format that can be logically tested or downloaded to a target device






40. Dual in - line memory module






41. 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.
