<span style>Hello, i'm having problems trying the beamformer analysis with a frequency band of interest. I would like to have for example an interval like [8 14] Hz. My concept problem is about the cfg.frequency and cfg.tapsmofrq values. (it must be a escalar, but i want a frequency band). </span><div style>
<br></div><div style>%FREQ ANALYSIS</div><div style><div>cfg = [];</div><div>cfg.method = 'mtmfft';</div><div>cfg.output = 'powandcsd';</div><div>cfg.tapsmofrq = 5;</div><div>cfg.foilim = [8 14];</div>
<div>freq_words_alpha = ft_freqanalysis(cfg, words);</div></div><div style><br></div><div style><br></div><div style>%SOURCE ANALYSIS</div><div style><div>cfg = []; </div><div>cfg.frequency = 11; </div><div>

<div>cfg.grid = grid; </div><div>cfg.reducerank = 2;</div><div>cfg.vol = vol02;</div><div>vol02=ft_convert_units(vol02,'cm');</div><div>source_pre11 = ft_sourceanalysis(cfg, freq_words_alpha );</div>
</div><div style><br></div><div style><br></div><div style>I use a cfg.frequency of 11 but i don't have really clear what i'm doing as a get the same result using cfg.frequency=11 but a freqanalysis in [10 12]. I would be very grateful if someone could solve my doubt.</div>
