Delay for n samples#

Unit Delay for n samples implements delay of input value by specified number of sampling steps. The minimum number of delay steps is 1. The block allows to specify three different types of sampling:

The block allows you to specify three different types of discretization:

Fundamental project frequency decimation - the output signal has a sampling rate N times less than the sampling rate of the project (the inverse of the integration step). Here, N is a given design fundamental sampling rate decimation factor, N ≥ 1.

Sample time is the interval between time points at which the input signal values are sampled. The value of the specified sampling period shall be a multiple of the integration step specified in the project.

Sampling frequency - sampling rate of input signal values. The value of the specified sampling frequency shall be a divider of the sampling frequency specified in the design (the value opposite to the integration step).
