Hi Gnuradio folks,
i am analysing the spectrum from 1MHz to 2Mhz. I splitted this Spectrum
into 3 parts:
1MHz - 1,333MHz
1,333MHz - 1,666MHz
1,666MHz - 2MHz
Therefore i used the Analysis Filterbank. Because i am searching for si
in the time domain as a response of a peak in the frequency domain, i
to use a band pass filter in the Analysis Filterbank.
Do i have to use the band pass filter or can i sill use the low pass
The response should be another one by using the Low pass filter ?
But my main Problem is, that my signal goes down in the second and third
I doesn’t know why.
Here is my Flow Graph:
Usrp Source --> Analysis Filterbank+Band pass filter --> Selector -->
fft sink graph
My band pass looks like this:
Intermediate Frequency of the usrp= 1MHz
firdes.complex_band_pass(1.0, samp_rate, samp_rate0, samp_rate1/3,
Any hints how to correct this ?
Did i anything wrong ?
