Sampler Icon

`Sampler`

Clock-agnostic sampler block.

Samples the continuous-time input signal u onto the clock of the output y, so that y takes the value of u at every tick of that clock. The clock of y is inferred from the discrete-time context that y is connected to; the block declares no sample interval of its own.

Before the clock of y has ticked, y equals initial_condition.

Usage

DiscreteComponents.Sampler(initial_condition=0)

Parameters:

Name	Description	Units	Default value
`initial_condition`	The value of `y` before the clock of `y` has ticked	–	0

Connectors

u - This connector represents a real signal as an input to a component (RealInput)
y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

Behavior of this component cannot be rendered because it includes path variables.
