Which statement best describes the role of signal conditioning in a sensor system?

Signal conditioning shapes and converts what a sensor outputs so the controller can read it accurately and reliably. Raw sensor signals are often tiny, noisy, offset, and mismatched to the controller’s input range. Conditioning provides amplification to bring the signal into the ADC’s usable range, filtering to reduce noise and unwanted frequencies, offset and linearization adjustments, isolation to protect the system, and impedance matching to prevent loading the source. All of these steps together make the signal ready for reliable processing by the controller, which is why this description fits best. It’s not about boosting the power supply, it’s about making the sensor’s signal usable for the next stage.
