Signal\Discrete
Domains: Discrete. Size: 1-D. Kind: Block Diagrams.
This model represents a discrete summation operator:
output(k) = initial;
with k = 0
outp(k) = inp(k-T) + inp(k-2T) + inp(k-3T) + ...+ inp(0) + initial
with k = n * T , n = 1,2,3,...
The sampletime T can be set in the Simulator (choose Properties, Simulation and Discrete System).

The input and output of this model are discrete signals. 20-sim will automatically detect the existence of discrete models. Each chain of discrete models will be assigned a specific sampletime. You can set this sample time to any desired value in the Simulator (choose Properties, Simulation and Discrete System).
