The video is a primer on encoder design, walking you through the basics of sensing rotation with phototransistors, and how a pair of detectors is needed to determine the direction of rotation.

In linear encoders for NC applications, external electronics interpolate sinusoidal signals from the encoder head. The effect is to subdivide the basic line spacing on the scale to gauge smaller ...

Battery backups can help eliminate the need for re-homing after planned or unplanned shutdowns. Incremental encoders are typically simpler to use and cheaper than absolute encoders.

(See Figure 1.) Figure 1 Encoder Basics The old analog modulator takes in one source, typically baseband audio and video, and creates an analog carrier for those signals to ride on. Composite Video, ...
