Integer Delay

Delay a signal N sample periods

Library

Discrete

Description

The Integer Delay block delays its input by N sample periods.

The block accepts one input and generates one output, both of which can be scalar or vector. If the input is a vector, all elements of the vector are delayed by the same sample period.

Data Type Support

The Integer Delay block accepts signals of any data type supported by Simulink, including fixed-point data types.

Parameters and Dialog Box

Initial condition

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.

Sample time (-1 for inherited)

Specify the time interval between samples. To inherit the sample time, set this parameter to -1. See Specifying Sample Time in the online documentation for more information.

Number of delays

The number of periods to delay the input signal.

Characteristics

Direct Feedthrough	No
Sample Time	Specified in the Sample time parameter
Scalar Expansion	Yes, of input or initial conditions

Inport

Integrator
