Difference between Low and High pass filter on Touch input

[markinjapan]

Hi,

Can someone explain the fundamental difference between low and high pass filtering?  (on a Vector3)

I'm using touch to drag a camera but when I start dragging, the camera jumps slightly every time. I'm using 0.25 low pass filtering but it still jumps slightly. It could be my FSM but I'd like to know what the difference is anyway.

Thanks
