7.5.4  Analog encoder (Sin-Cos encoder) interface

The Titan Go can use analog encoder (also known as Sin-Cos encoder) as position and velocity feedback element. 

This sensor provide a pair of quadrature sine and cosine signals as the motor moves, which frequency depends on 

the motor speed. The signals may be generated by optical or magnetic means. For noise immunity the signals are 
typically transmitted differentially from the encoder to the sensor interface electronics.
