Q41
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.
Answer: Option B
Q42
The direct drive mode of a stepper motor allows for less control by the operator.
Answer: Option B
Q43
In the frequency counter, a pulse shaper block is needed to ensure that the unknown signal, whose frequency is to be measured, will be compatible with the clock input for the counter block.
Answer: Option A
Q44
In the digital clock project, the AHDL block codes are connected using graphic design files.
Answer: Option A
Q45
In HDL, one of the strategies used in strategic planning is to find the speed requirements.
Answer: Option B
Q46
In the keypad HDL encoder, the ts bit array represents a tristate buffer.
Answer: Option A
Q47
In the VHDL code of the stepper motor, the cout outputs are bit_vector type because they are binary bit patterns.
Answer: Option A
Q48
In the keypad HDL encoder, as long as all columns are high the ring counter is enabled and counting.
Answer: Option A
Q49
In the frequency counter, the pulse width of the enable signal is very critical for taking an accurate frequency measurement.
Answer: Option A
Q50
One of the first steps in any HDL project is to define its scope by naming each input and output.
Answer: Option A
