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 type of magnetic tape format






2. Describes a number system with a base of ten






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






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






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






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






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






8. An electrical instrument used to measure current






9. A type of IC package whose leads must pass through holes to the other side of a PC board






10. 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






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






12. 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.






13. A digital counter having ten states






14. A method of analog- to- digital conversion using a 1- bit quantization process






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






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






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






18. A receiving device on a bus






19. A bridge circuit that is in the balanced state as indicated by 0 V across the output.






20. The graph of a filter's frequency response showing the change in the output voltage to input voltage ratio expressed in dB as a function of frequency for a constant input voltage






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






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

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






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






25. In addition (ORing) and multiplication (ANDing) of two variables the order in which the variables are ORed or ANDed makes no difference






26. 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






27. 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.






28. A binary digit - which can be either 1 or 0






29. A combined coder and decoder






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






31. The effect created when a signal is sampled at less than twice the signal frequency. Aliasing creates unwanted frequencies that interfere with the signal frequency.






32. A group of eight bits






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






34. The number of protons in a nucleus






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






36. A circuit with a complete current path






37. In a division operation the quantity that is being divided






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






39. 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.






40. Having two opposites charge carriers within the transistor structure






41. A digital circuit device that converts coded information into another (familiar) or noncoded form






42. An expression of variables and operators used to express the operation of a logic circuit






43. The current left after the total load current is subtracted from the total current into the circuit






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






45. The unit of electrical current






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






47. Dual in - line memory module






48. Dynamic random- access memory; a type of semiconductor memory that uses capacitors as the storage elements and is a volatile - read/write memory






49. Data Terminal equipment






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