I'm currently reading this paper: http://www.rssd.esa.int/SP/LISAPATHFINDER/docs/Data_Analysis/GH_FFT.pdf
On page 21, it has a section called "Putting it all together", it states the following steps:
Frequency resolution and length of DFT
Splitting of the data stream
Now, the "Window function" is mapped out before the "Splitting of the data stream" if this is the case, should I therefore multiply each of the bins within the data stream by each of the window values (Hanning)?
For example, at the moment, my Hanning window size is:
256 and the data is split into segments of size 256x128 in this case..
N = size of stream and then compute
I've seem a lot of DSP engineers split the window up into frames, before applying the window?
