WebJul 7, 2024 · In simple words, the comparator is a basic operational amplifier used to compare two voltages simultaneously and changes the o/p according to the comparison. … An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are … See more The first commercial comparator was developed by James Hartness and Russell W. Porter. Hartness' long-continuing work as the Chairman of the U.S.'s National Screw-Thread Commission led him to apply his familiarity … See more The projector magnifies the profile of the specimen, and displays this on the built-in projection screen. On this screen there is typically a grid that can be rotated 360 degrees so the X-Y axis of the screen can be aligned with a straight edge of the machined part to … See more • Shadowgraph See more The profile projector is widely used for complex-shape stampings, gears, cams, threads and comparing the measured contour model. The … See more Projection methods 1. Vertical projectors: The main axis is parallel to the plane of the screen. They're most common, and suitable for flat parts or smaller work … See more

This is an arrangement of transistors which amplifies the difference between two signals, presents a high input impedance (especially if MOSFET), and usually somewhat rejects any common voltage. In circuit terms the long-tailed pair is close to the input of the comparator. bitmap must not be null
