Domains: Discrete. Size: 1-D. Kind: Block Diagrams.

Description

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).

Parameters

 

initial

Initial value of the output.

Limitations

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).
