FIR Simulink

Hello,

Another wonderfull noob question, So I designed a basic filter with FDAtool and then converted it to a simulink block. Now I want to test my filter in simulink, to see if it works.

So what blocks should I add? I know I need some sort of samples as imput and also a way to read the samples out. But I tryed alot of things, non of them worked.

I designed a Window Taylor FIR bandstop on 5Khz, (if i can get the same graph or something else as on FDAtool its also good)

Thanks alot!

This example on Digital Filters may be a useful starting point for you. Essentially, you can use one of the many Simulink sources (Sine Wave, etc.) to test your filter.

I'm more looking for a way to send a unity response or pulse through the filter so I can get the filters response back.

The closest thing to get an impulse response is using the Pulse Generator block with a large period.
