Consider a digital system wkt y=mx(n)+c(where y is the response,x(n) is the input ,n is discrete time and c is some constant)
is a linear equation but it disobeys principle of superposition and thus the system is considered non linear.does it mean that superposition principle fails to explain its linearity in this case or what??.I can't understand the intricacies of the difference these 2 (linearity as defined by superposition principle and linearity as defined by characteristics)
