The Schmitt Trigger and How It Works
Whether because of harsh environments or the inherent limitations of sensor technology, output signals are rarely as clean as we'd like. Sensor noise can overwhelm a navigation system or even a simple robotics control system. You can take steps such as adding shielding to cables (adds weight), defining noise gates in software (takes space and degrades overall computational performance), and investing in better, more expensive sensors.
