2.2. Early Approaches to Testing (1940s – 1960s)

Try these first

1. 1.

   What is visual inspection?

   Hint

   Think about how you would check for visible faults in a device.

2. 2.

   Define functional testing.

   Hint

   Consider what it means to check if a circuit does what it's supposed to do.

3. 3.

   What is the primary limitation of visual inspection?

   • It's too expensive
   • It's slow and prone to errors
   • It's always accurate

   Hint

   Think about how quick assessments are made.

4. 4.

   True or False: Functional testing can check individual components of a circuit effectively.

   • True
   • False

   Hint

   Focus on the purpose of functional testing.

5. 5.

   Design a simple testing protocol for an old circuit board using the early methods described. What steps would you include, and why?

   Hint

   Think about the logical steps in a physical assessment.

6. 6.

   Critically analyze the transition from early manual testing methods to automated testing techniques in the context of circuit complexity.

   Hint

   Consider how advancements drive change.
