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 ...

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 ...

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 ...

Vying for position as a contactless alternative to mechanical rotary switches, the AS5030 and AS5130 8-bit absolute magnetic rotary encoders integrate push button and low-power mode features. Both ...

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 ...
