Questions and Answers

1.

DET is better than Quasi tester in detecting unstable readers.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
DET is not better than Quasi tester in detecting unstable readers.

2.

Quasi testing is not a physical measurement of track geometries as DET.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Quasi testing refers to a method of testing that does not involve physical measurements of track geometries, unlike DET (Defect Entry and Tracking). Therefore, the statement "Quasi testing is not a physical measurement of track geometries as DET" is true.

3.

Rc is a measured Head Cold Resistance.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The given statement states that "Rc is a measured Head Cold Resistance." This implies that Rc is indeed a measured resistance specifically for head colds. Therefore, the correct answer is "True."

In the Quasi's Noise Measurement Circuit, the PRE-AMP acts as:
- A.
  
  Voltage Regulator
- B.
  
  Input Impedance
- C.
  
  Current Sense Amplifier
Correct Answer
C. Current Sense Amplifier

Explanation
The PRE-AMP in the Quasi's Noise Measurement Circuit acts as a current sense amplifier. A current sense amplifier is a type of operational amplifier that amplifies the small voltage drop across a sense resistor to measure the current flowing through it. In this circuit, the PRE-AMP is responsible for amplifying the small voltage drop across the sense resistor, allowing for accurate measurement of the current.

It is the voltage change to follow resistance moves by Magnetic Field.
- A.
  
  Resistance
- B.
  
  Voltage
- C.
  
  Current
- D.
  
  Amplitude
Correct Answer
D. Amplitude
6.

Another term for 0 (Zero) Kurtosis:
- A.
  
  Gaussian
- B.
  
  Attribute
- C.
  
  Mean
- D.
  
  Kaizen
Correct Answer
A. Gaussian

Explanation
Gaussian is another term for 0 (Zero) Kurtosis. Kurtosis measures the shape of a distribution and indicates how the data is distributed around the mean. A kurtosis value of 0 indicates that the distribution has the same shape as a normal distribution, also known as a Gaussian distribution. Therefore, the correct answer is Gaussian.

7.

It has an accurate measurement of ELG Resistance. DET or QUASI?

Correct Answer
Quasi

Explanation
The correct answer is "Quasi" because the question is asking about the accuracy of the measurement of ELG Resistance. "Quasi" means that the measurement is almost accurate or close to being accurate. This suggests that the ELG Resistance measurement is not completely accurate, but it is still reliable enough to be considered quasi-accurate.

8.

It is used for noise excitation as acceleration. Magnetic Field or Amplitude?

Correct Answer
Magnetic Field

Explanation
In the given question, the term "noise excitation as acceleration" suggests that we are looking for a quantity that is used to generate noise or vibrations. Amplitude refers to the magnitude or intensity of a signal, while Magnetic Field is a physical quantity that can be used to induce vibrations or noise in certain systems. Therefore, Magnetic Field is the correct answer as it is used for noise excitation as acceleration.

9.

Quasi measurements compliment DET.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Quasi measurements complement DET, meaning they enhance or supplement the use of Design of Experiments and Testing (DET) techniques. Quasi measurements are often used when it is not feasible or practical to directly measure certain variables or conditions. They involve indirect or approximate measurements that provide useful information for analysis and decision-making. By combining quasi measurements with DET, a more comprehensive understanding of the system or process under investigation can be achieved, leading to improved insights and better outcomes. Therefore, the statement "Quasi measurements complement DET" is true.

Rate this question:
10.

One of the noise measurement steps is to compute the gain correction factor.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
In noise measurement, it is necessary to compute the gain correction factor. This factor helps in adjusting the measured noise levels to account for any amplification or attenuation introduced by the measurement equipment. By applying the gain correction factor, accurate and reliable noise measurements can be obtained. Therefore, the statement that one of the noise measurement steps is to compute the gain correction factor is true.
