My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

While standard optical encoders have traditionally been used to meet the needs of high-precision sensing and control applications (such as steering-wheel position detection or industrial motion ...

The AS5035 8-bit magnetic rotary encoder provides incremental quadrature A/B output as well as an index output. The part offers 64 pulses per revolution and operates at rotational speeds up to 10,000 ...

A DSP design approach, including hardware and software implementation for a quasi-absolute encoder. LEE WEI YAN, Applications Engineer, Avago Technologies, San Jose, Calif. A high-accuracy 20-bit ...
