 		 #105122 - absolute encoders
Responding to: ???'s previous message
OK I thought this is the case and it is and ubeatable argument... As I said, I know nothing on the topic.

Just out of interest, what are the approximate price relationships between absolute and relative encoders (perhaps including thh signal conditioning circuitry and the decoder's cost for the latter)?
