Digital System Projects Using HDL problems

  • 1. The full-step sequence always has two coils of the stepper motor energized in any state of the sequence and typically causes 30° of shaft rotation per step.

  • Options
  • A. True
  • B. False
    • Discuss
  • 2. In the digital clock project, the AHDL block codes are connected using graphic design files.

  • Options
  • A. True
  • B. False
    • Discuss
  • 3. One of the first steps in any HDL project is to define its scope by knowing the nature of all the signals that are interconnected to pieces of the project.

  • Options
  • A. True
  • B. False
    • Discuss
  • 4. In the keypad HDL encoder, the data signal is used to combine the row and column encoder data to make a 4-bit value representing the key that was pressed.

  • Options
  • A. True
  • B. False
    • Discuss
  • 5. In the VHDL code of the stepper motor, the cout outputs are bit_vector type because they are binary bit patterns.

  • Options
  • A. True
  • B. False
    • Discuss
  • 6. In HDL, one of the strategies used in strategic planning is to find the speed requirements.

  • Options
  • A. True
  • B. False
    • Discuss
  • 7. In the digital clock project, frequency prescaling is used to take a 1 pps input and transform it into a 60 pps timing signal.

  • Options
  • A. True
  • B. False
    • Discuss
  • 8. The direct drive mode of a stepper motor allows for less control by the operator.

  • Options
  • A. True
  • B. False
    • Discuss
  • 9. In the keypad HDL encoder, the freeze bit detects when a key is released.

  • Options
  • A. True
  • B. False
    • Discuss
  • 10. The half-step sequence of a stepper motor is created by inserting a start with only one coil energized between full steps.

  • Options
  • A. True
  • B. False
    • Discuss
