The block implements zero-order extrapolation:
where y(t) is the value of the output signal at the current moment of the calculated time (model time), x( t[k] ) is the value of the input signal at the time of sampling t[k]. Sampling occurs with a period T, which is set by the block parameter.

Inputs
- input - block input.
Outputs
- output - block output.
Properties
- Sampling period – block calculation sampling period.
Parameters
none
Note:
For the proper operation of this unit, it is necessary to set the maximum integration step no more than 0.5·T. When integrating with a constant step, it is recommended to set the step such that the sampling period is a multiple of the integration step T = k·h, where k, h is an integer and the integration step respectively.
