Sensor Signal Filtering

Design the signal chain from sensor output to reported value. Keep raw samples, filtered values, timing, saturation, and fault flags observable; a filter must not conceal a broken sensor or unsafe voltage.

Intake gate

Record or label unknowns before selecting a component or algorithm:

• exact board, MCU, core/framework, ADC channel, resolution, reference, input range, acquisition time, and toolchain versions
• sensor part/module, output type and drive impedance, supply, cable length, expected signal bandwidth, valid range, warm-up, and failure behavior
• sample period/jitter budget, acceptable latency, step-response requirement, threshold policy, calibration model, and available measurement tools
