Noise wars: Projected capacitance strikes back against internal noise

... to handle. With a traditional TFT (thin-film-transistor) LCD, either a dc or an ac voltage drives the common electrode. An ac common-electrode layer typically lowers the operating voltage of the display driver and keeps a constant voltage across the liquid crystal. The ac common-electrode layer finds use in relatively low-cost displays, consumes more power, and has a noisier profile than do dc common...

Qualitative to quantitative sensor transition challenges

...; different CTEs can be significant. Temperature gradients across the sensor are often ignored (see sidebar: Thermal sensitivities).Shocks and impulses: These are short term, broadband energy inputs.Electrical: Switch mode power supplies, system clocks, power switching systems.Background Noise: Road noise, bearing noise, non-laminar fluid flows, audio signals.There are several methods for eliminating, or at least...
