[QUOTE="Frank Koenig, post: 105963, member: 416"] Re: Audio / Log taper confusion Good point. The absolute nature of position from a pot can be a plus or a minus. On the plus side, there is no need for homing upon power-on -- persistent position memory, if you will. This is good for mission critical stuff, like position feedback on a missile vane servo, for example. As you point out, a gray-code digital encoder also gives absolute position, and I suppose these days there's a built in gray-to-serial encoder so that it's down to one or two wires no matter how many bits. I'm straying pretty for off topic here. Maybe I'm a little starved for this kind of talk :) --Frank [/QUOTE]
