Circular time shift property
Web2.16.2 Time Shift. Linear, shift invariant, discrete time system are invariant regarding shifts in their independent variables. This property permits the initial value of the independent variable to be arbitrarily set to zero () during the analysis of such systems. This can often simplify the analysis.
