Abstract Introduction
Absolute encoders using optical technology often face Avago Technologies has introduced a high accuracy 20-bit
limitations in resolution and size. For example, to achieve resolution quasi-absolute encoder, with DSP based signal
a higher resolution of up to 16-bits, the absolute encoder processing. This encoder is built into a housed PCBA with
has to be combined with an incremental pattern that is DC (direct current) stepper motor assembly and is able to
strongly interpolated with an external hardware and sig- operate in a wide operating ……
