LabVIEW
FFT LabView component
how do I find these 2 components in labview? I downloaded the Biomedical Toolkit, but I can't find them. please answer me. I have an urgent project to finish.

The upper item is a reference to a frontpanel element, the other one is a typedefined cluster control.
When you don't know such items I recommend to take those LabVIEW learning resources offered at the top of the LabVIEW board!

can you tell me the names of the components? so I can look for them by name? thank you very much
You can read the labels in your image!
There is a graph (or chart?) reference for a graph labelled "EEG Spectrum".
There is a cluster labelled "FFT settings" on the frontpanel.
- Why don't you look for those items in your VI?
- Why don't you double-click those items in the block diagram to find their frontpanel controls?
- Why don't you create that FFT settings cluster by right-clicking the corresponding input connector of a subVI/function asking for that cluster?
These are very basic LabVIEW steps: did you already look at the training resources offered at the top of the LabVIEW board?

the picture is found on a website, and I am trying to reproduce it for my project in labview.
when I searched directly by name, it did not find my components
Why don't you provide a link of that website so we all know what you are talking about?
I already told you twice what this items are!
You need to create a (waveform?) graph labelled "EEG Spectrum" and then a reference of that graph.
And you need to create that FFT settings cluster from its typedefinition…
As GerdW said, there's nothing special about the controls you show. These are just regular LabVIEW controls used in the Bio-Medical toolkit VIs. If you have that, just drop the EEG Spectrum Plot on your front panel and add a control for the FFT Settings. There are also Bio-Med VIs in the block diagram palette you can find them in the Toolkits palette. I've never used this toolkit since it requires some advanced signal processing packages which are expensive, but you can just download the evaluation if you want to check it out...

Neither of these items are something that you would find in any of the tool palettes.
EEG spectrum is a reference to a font panel object. You create a reference by right clicking on that objects terminal in the block diagram and selecting "Create" then "Reference" from the popup menu.
FFT Settings is a block diagram terminal for Type Def Cluster Control. One way to create this is to right click on the VI terminal it connects to and select "Create" then "Control" this will create the front panel object and the terminal on the block diagram.
If you didn't understand any of this I suggest you take some of the free training courses.
