Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...

Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

Comparators are one of the basic building blocks of analog and mixed-signal designs, providing one small but critical function, as their name indicates. Their role is often to be a “simple” safety ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Simple optics display the part upside down and backwards on the glass screen. Corrected optics display the part right side up and backwards. Fully corrected optics yield an image identical to the part ...

The diagrams of two simple balance-bridge devices are given, which allow for the comparing of two inductances with high accuracy. An LED indicator, or high-impedance telephone headphones, are used as ...

Inspecting with Optical Comparators provides an overview of the optical comparator, which uses optics to project an enlarged, two-dimensional shadow of a part onto a glass screen for measurement of ...
