This box can be used in conjunction with the Spectral Analysis and
the Frequency Band Selector boxes in order to compute a power in specific
frequency bands of a spectrum. The output is a column matrix giving a single value for each
channel : the actual average power of the spectrum. You can may want to use these values
with the Simple DSP to get ratios.
This input should connect to a spectrum stream, either filtered with the
Frequency Band Selector box or not.
The output is a column matrix giving a single value for each
channel : the actual average power of the spectrum.
The Frequency Band Selector outputs a spectrum with
all initial frequency band represented. The bands that were not selected
just have a 0 instead of their value. Consequently, you can use this settings
to tell the box if the 0s contained in the spectrum should be part of the
mean or not.
