This examination will asses the learner's knowledge and understanding of the topic Quasi Testing and will provide certification upon completion.

• 1.

### DET is better than Quasi tester in detecting unstable readers. TRUE or FALSE?

• A.

True

• B.

False

B. False
Explanation
The statement "DET is better than Quasi tester in detecting unstable readers" is false. This means that DET is not better than Quasi tester in detecting unstable readers.

### Quasi testing is not a physical measurement of track geometries as DET. TRUE or FALSE?

• A.

True

• B.

False

A. True
Explanation
Quasi testing is indeed not a physical measurement of track geometries like DET. This means that the statement "Quasi testing is not a physical measurement of track geometries as DET" is true. Quasi testing refers to a form of testing that simulates certain aspects of the real environment or system behavior, without fully replicating it. In the context of track geometries, quasi testing would involve using models or simulations to evaluate the performance and characteristics of the track, rather than physically measuring it.

### Rc is a measured Head Cold Resistance. TRUE or FALSE?

• A.

True

• B.

False

A. True
Explanation
The given correct answer is true because the question states that "Rc is a measured Head Cold Resistance." This implies that Rc is indeed a measured head cold resistance, indicating that the statement is true.

### (Choose letter of yor choice)In the Quasi's Noise Measurement Circuit, the PRE-AMP acts as:

• A.

A. Voltage Regulator

• B.

B. Input Impedance

• C.

C. Current Sense Amplifier

C. C. Current Sense Amplifier
Explanation
In the Quasi's Noise Measurement Circuit, the PRE-AMP acts as a current sense amplifier. This means that it amplifies the small current signal produced by the noise source, allowing for more accurate measurement and analysis of the noise. The current sense amplifier is responsible for converting the small current signal into a larger voltage signal that can be easily measured and analyzed.

• 5.

### (Choose letter of yor choice)It is the voltage change to follow resistance moves by Magnetic Field.

• A.

A. Resistance

• B.

B. Voltage

• C.

C. Current

• D.

D. Amplitude

D. D. Amplitude
Explanation
The correct answer is d. Amplitude. Amplitude refers to the maximum value of a voltage or current waveform. In this context, it suggests that the voltage change is directly proportional to the movement of resistance caused by a magnetic field. This implies that as the resistance moves, the voltage also changes in amplitude.

• 6.

### (Choose letter of your choice)Another term for 0 (Zero) Kurtosis:

• A.

A. Gaussian

• B.

B. Attribute

• C.

C. Mean

• D.

D. Kaizen

A. A. Gaussian
Explanation
Zero (Zero) Kurtosis is another term for Gaussian. Gaussian distribution, also known as the normal distribution, is a symmetric probability distribution that is commonly used to model random variables. A distribution with zero kurtosis indicates that the data has a normal distribution, with a bell-shaped curve and no significant outliers. Therefore, the correct answer is a. Gaussian.

Rate this question:

• 7.

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

Quasi
Explanation
The correct answer is "Quasi" because the question is asking about the measurement of ELG Resistance. Quasi refers to a type of measurement that is not exact or precise, but rather approximate or close to the actual value. Therefore, it can be inferred that the measurement of ELG Resistance is not accurate but rather a close approximation.

Rate this question:

• 8.

### It is used for noise excitation as acceleration.

• A.

A. Magnetic Field

• B.

B. Amplitude

A. A. Magnetic Field
Explanation
This answer suggests that the given statement is referring to the use of a magnetic field for the purpose of exciting noise as acceleration.

Rate this question:

• 9.

### Quasi measurements compliment DET. TRUE or FALSE?

• A.

True

• B.

False

A. True
Explanation
Quasi measurements complement DET. This means that quasi measurements can be used in conjunction with DET (Defect Escape Trending) to provide additional information or insights. Quasi measurements are typically subjective or indirect measurements that are used when direct measurements are not available or feasible. By using both quasi measurements and DET, a more comprehensive understanding of the defect escape trends can be obtained, leading to better decision-making and problem-solving in the context of quality control and improvement.

Rate this question:

• 10.

### One of the noise measurement steps is to compute the gain correction factor. TRUE or FALSE?

• A.

True

• B.

False

A. True
Explanation
The statement is true because computing the gain correction factor is indeed one of the steps in noise measurement. The gain correction factor is used to adjust the measured noise levels to account for any amplification or attenuation in the system. By applying this correction factor, the noise measurements can be more accurately compared and analyzed across different systems or devices.
