Summing amplifier ? choose the output interpretation. Use this to support: Describe the function of an astable circuit.
- A.summing amplifier: the output depends on the weighted sum of input currents through the input resistors for Astables.
- B.summing amplifier: uses one sensor only.
- C.summing amplifier: reverses all resistor roles.
- D.summing amplifier: describes a single logic input.
Model answer
What a good answer should say
- The correct option is summing amplifier: the output depends on the weighted sum of input currents through the input resistors for Astables.
Explanation
Why this works
This is the best answer because the summing amplifier context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for Astables.
