Which topology involves two independent inputs merging into a single output?

• A. Convergent
• B. Divergent
• C. Linear
• D. Feedback

Answer: (A)

The idea here is about how signals are routed and combined. A convergent topology is one where multiple inputs come together to form a single output—think of two separate signals being mixed or summed into one line, like a mixer or adder in a control or signal path. That’s exactly what the question describes: two independent inputs merging into a single output.

In contrast, a divergent topology would take a single input and split it into multiple outputs; linear refers to how the system responds to inputs (superposition and proportionality) rather than how paths merge or split; and feedback involves routing part of the output back to influence the input, not about combining multiple inputs into one path.
