Options- A. Magnetic disk
- B. Magnetic tape
- C. Magneto-optical disk
- D. Optical disk Discuss
- 2. Which is not a hard disk performance parameter?
Options- A. Seek time
- B. Break time
- C. Latency period
- D. Access time Discuss
- 3. How many 8 k × 1 RAMs are required to achieve a memory with a word capacity of 8 k and a word length of eight bits?
Options- A. Eight
- B. Four
- C. Two
- D. One Discuss
- 4. What is a multitap digital delay line?
Options- A. a series of inverter gates with RC circuits between each one
- B. a series of inverter gates with RL circuits between each one
- C. a series of NAND gates with RC circuits between each one
- D. a series of NAND gates with RL circuits between each one Discuss
- 5. Dynamic memory cells store a data bit in a ________.
Options- A. diode
- B. resistor
- C. capacitor
- D. flip-flop Discuss
- 6. How many address bits are required for a 4096-bit memory organized as a 512 × 8 memory?
Options- A. 2
- B. 4
- C. 8
- D. 9 Discuss
- 7. A transducer is a device that:
Options- A. converts a physical variable to an electrical variable
- B. converts analog data to meaningful data
- C. controls a physical variable
- D. stores digital data and then processes that data according to a set of specified instructions Discuss
- 8. The basic approach to testing D/A converters is to:
Options- A. apply a sequence of binary codes covering the full range of input values to the circuit input while observing the output on an oscilloscope. The output should consist of a linear stairstep ramp.
- B. single-step the device through its full input range while checking the output with a DMM.
- C. check the output with zero input and then full input. The output of the converter should extend from zero to its maximum value. If so, then everything in between can be assumed to be operating properly.
- D. apply the correct input to the analog terminal and then check to see if the proper binary code exists on the digital inputs. Discuss
- 9. Inaccurate A/D conversion may be due to:
Options- A. constant analog input voltage
- B. linear ramp usage
- C. intermittent counter inputs
- D. faulty sample-and-hold circuitry Discuss
- 10. What is the maximum conversion time for an 8-bit successive-approximation ADC with a clock frequency of 20 kHz?
Options- A. 12.8 ms
- B. 6.4 ms
- C. 0.05 ms
- D. 0.4 ms Discuss
