accoriding to my understanding both filters and window functions will make changes to the input signal parameters, according to wiki,
a filter is a device or process that removes from a signal some unwanted component or feature
a window function (also known as an apodization function or tapering function) is a mathematical function that is zero-valued outside of some chosen interval.
What I'm trying to understand is this,
- Where do we use these windowing functions & Filters in practical world?
- Do I need to use both for better signal quality, if so which one come first(
