Hi,
I'm not very clear on the relationship you are trying to establish between angle and speed. Is this some rotational measurement, or something regarding angular velocity? In any case, can you provide what your stimulus signal would be represented by and what your response signal would be? If you can determine this, then the Transfer Function should be fairly straightforward to use. Please provide me with some more details on what you are trying to do with "angle" and "speed". Thanks!
