Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why would you need to test a theory on a problem?
A
To identify the fault
B
To get a solution to the problem
C
To see if there are any other faults
D
None of the above
Explanation: 

Detailed explanation-1: -Fault detection plays an important role in high-cost and safety-critical processes. Early detection of process faults can help avoid abnormal event progression. Fault detection can be accomplished through various means.

Detailed explanation-2: -Fault identification. The purpose of fault identification is to understand the underlying failure mode, determine the size of the fault, and find its root cause.

Detailed explanation-3: -Fault diagnosis is the process of tracing a fault by means of its symptoms, applying knowledge, and analyzing test results.

Detailed explanation-4: -Built-in self-test (BIST) is a tech-nique that modifies the IC by embedding test mecha-nisms directly into it. BIST is often used to detect faults before the system is shipped and is potentially a very efficient way to implement on-line testing.
