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

Description

This is the the z-delay function with n samples delay.

 

output(k) = input(k - n*T)

with k = n * T , n = 1,2,3,...

 

The sampletime T can be set in the Simulator (choose Properties, Simulation and Discrete System).

Inputs

Description

input

 

Outputs

 

output

 

Initial Values

 

output_initial

The initial value of the block.

Parameters

 

n

The number of sample delays (n = 1,2,3,..).

Limitations

The parameter n can not be changed during simulation. If it is increased, recoompiling of the model is necessary.
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).
