Re: Encoder Basics
Just jumping in here, TTL is a signal level, not how the output is driven. There are basically 4 signal levels for quadrature encoders, 1vPP, 11uAPP, TTL, and HTL. The first two are usually sine wave output quadrature and have to go through an interpolator box to be converter to standard quad output...
