Simulink Discrete Filter Sample Time

Hello everybody I'm new here and new to simulink.

I have a problem

The Sample Time was "canceld" for the discrete Filter in the update 2023b.

At least the easy Set Up trough the Block Parameter, but I need it to initiated for the Task In Simu Link Fundamentals at step 4.5.

Does anyone know what i can do know? that would made my day.

Thank you

Best Regards

Jan

if the before answer can't solve your problem, do the next steps.

1) Right click on the Discrete Filter

2)Search the "Find Referenced Variables" option

3)Select "SimulinksFundamentales"

Now you can edit the parameter sample Time of the row Discrete Filter.

If in the beginning don't appear, do click on "show details". Then search the sample time option.

I have the same question. Thanks for the answer. It works now.

See the note on this page.

To set it in command line

set_param('BlockPath','SampleTime','0.1')

R2023b: Conditional display of the Sample time parameter

The Discrete Filter block no longer displays the Sample time parameter in the block parameters dialog box by default. The parameter is visible only if you set the sample time to a value other the default value (-1) at the command line or in an existing model. For more information, see Blocks for Which Sample Time Is Not Recommended.
