Delay scalar signal multiple sample periods and output all delayed versions
The Tapped Delay block delays an input by the specified number of sample periods and outputs all the delayed versions. Use this block to discretize a signal in time or resample a signal at a different rate.
The block accepts one scalar input and generates an output vector that contains each delay. Specify the order of the delays in the output vector with the Order output vector starting with parameter:
Oldest orders the output
vector starting with the oldest delay version and ending with the
newest delay version.
Newest orders the output
vector starting with the newest delay version and ending with the
oldest delay version.
Specify the output vector for the first sampling period with the Initial condition parameter. Careful selection of this parameter can minimize unwanted output behavior.
Specify the time between samples with the Sample time parameter.
Specify the number of delays with the Number of delays parameter.
A value of
-1 instructs the block to inherit the
number of delays by back propagation. Each delay is equivalent to
the z-1 discrete-time operator, which the Unit Delay block represents.
The Tapped Delay block accepts signals of the following data types:
For more information, see Data Types Supported by Simulink in the Simulink® documentation.
Specify the initial output of the simulation. The Initial
condition parameter is converted from a double to the input
data type offline using round-to-nearest and saturation. Simulink software
does not allow you to set the initial condition of this block to
Specify the time interval between samples. To inherit the sample
time, set this parameter to
-1. See Specify Sample Time in
the online Simulink documentation for more information.
Specify the number of discrete-time operators.
Specify whether to output the oldest delay version first, or the newest delay version first.
Select to include the current input in the output vector.
