| As shown in figure "B" of the illustrated analog PID controller, what is the primary purpose of "U3"? |
| A) to produce a signal voltage that is proportional to error signal voltage |
| B) to produce a signal voltage that is proportional to the sum of all past error signal voltages multiplied by time |
| C) to produce a signal voltage that is proportional to the rate of change of the current error signal voltage |
| D) to produce an error signal that is the difference between the process variable feedback signal voltage and the setpoint signal voltage |

| If "U3" is part of the proportional control Football Bros path, it produces a signal voltage proportional to the error signal voltage. This output represents the immediate response to the current error. |
