Library of blocks that operate on periodically and non-periodically clocked signals
Extends from Modelica.Icons.Package (Icon for standard packages).
Name | Description |
---|---|
IntegerChange | Indicate Integer signal changing |
UnitDelay | Delay the clocked input signal for one sample period |
FractionalDelay | Delay the clocked input signal for a fractional multiple of the sample period |
Indicate Integer signal changing
This block is a synchronous version of
Modelica.Blocks.Math.IntegerChange.
It uses previous
instead of the implicit pre
of
change
to set the Boolean output y
to
true
when the integer input u
changed. Thus, it's
logic is:
if firstTick() then y = false; else y = not (u == previous(u)); end if;
This block might be superfluous and replaced by
Modelica.Blocks.Math.IntegerChange
when the semantics
of change
are relaxed and well-defined for
clocked discrete-time partitions.
Extends from Clocked.ClockSignals.Interfaces.ClockedBlockIcon (Basic graphical layout of block where at least one input or output is a clocked variable).

Delay the clocked input signal for one sample period
This block describes a unit delay:
// Time domain description y(ti) = previous(u(ti)) // Discrete transfer function 1 y(z) = --- * u(z) z
that is, the output signal y is the input signal u at the previous clock tick. At the first clock tick, the output y is set to parameter y_start.
