Dear all,
Hello. I want to clarify a basic algorithm when using [temporal filter] box.
Now I desigend scenario with [aquisition server] -> [time based epoching] -> [matlab scripting box]
Most signal processing is done in [matlab scripting box].
I considered using [temporal filter], but small questions appeared.
I know that temproal filter will filter as much as epoched data passing through [time based epoching] box
when I design scenario as [time based epoching] -> [temporal filter].
On the other hand, when I design scenario as [temporal filter] -> [time based epoching],
how [temporal filter] works? only filtering as much as chunck size? or sliding window?
Sorry, it seems very basic question, but I could not find the answer here and documentation
Maybe I missed something.
Best regards,
Kyungho Won

Re: Basic question - how temporal filter box works
Hi, afaik temporal filter has a state that evolves over time. When a new chunk is obtained, the previous state is used, the chunk is filtered and the state is updated.
That said, I definitely recommend using the temporal filter before any epoching operations. This way the risk of artifacts due to noncontinuous chunks is removed.
