A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...
Absolute encoders using optical technology often face limitations in resolution and size. For example, to achieve a higher resolution of up to 16-bits, the absolute encoder has to be combined with an ...
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 ...
Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...
As portable handheld communication devices proliferate, vendors are adding more features, such as digital video and audio, to meet consumer demand. The ISO MPEG-4 standard is emerging as the ...
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 ...
