Abstract
In this short note we compare Mishchenko's definition of noncommutative signature for a manifold with proper -action of a discrete, countable group with the (more analytical) counterpart defined by Higson and Roe in the series of articles "Mapping Surgery to Analysis". A generalization of the coarse index is also addressed.
