Optical comparators are instruments that project a magnified image or profile of a part onto a screen for comparison to a standard overlay profile or scale. They are noncontact devices that function ...

There are only 17 days left until IMTS 2016 kicks off in Chicago. Here are just a few of the quality tools you can expect to see on the show floor. (Image courtesy of Mahr Federal.) Mahr Federal’s new ...

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 ...

Testing a set of analog comparators for hysteresis can be a time-consuming process. You have to accurately find the threshold voltages for numerous devices across variations in fabrication process, ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...

Digital comparison is considered an important method used in digital systems while executing arithmetic or logical operations. It’s designed to compare the relative magnitudes of binary numbers. This ...
