Further on my graphic does not look like my spectrum in the
FFT-sink.
A FFT sink displays the frequency domain, it's amplitude versus frequency.
Printing the samples shows the time domain, amplitude versus time.
The FFT sink feeds the samples through a FFT-block, resulting in its name.
A scope sink just plots the samples, as you try with Matlab/Octave.
You are right, thats also what i am thinking, but to these
samples through a fft, i have to know what is a sample !
Thats the topic of this post.
Thats what i not understand.
What is a sample ?
For example, is this ONE sample ?
24 + 5i
The left is a 32bit I part and the right is the Q part ?
But as i read I and Q are complex, so i sink I and Q will
be changed from line to line ?
If i need more than one line for one sample, how many lines
do i need for the fft ?
