Question 244General Subjects - 1st Asst/Chief

The correct answer is C) Low Select Signal Processor. The symbol "I" in control system diagrams represents a low select signal processor, which is a component that selects the lowest signal from multiple inputs. This allows the control system to prioritize the lowest value, which can be important for safety or other critical functions. The other options are incorrect because: A) High Select Signal Processor would select the highest signal, not the lowest; B) Integral Processor refers to a different component that performs integration calculations; and D) Difference Signal Processor would output the difference between two signals, not select the lowest.
