Hi Alejandro, what about vector to stream, and a deinterleave with block size = fftlen/2 ? Greetings Marcus On 03/21/2015 04:32 PM, Alejandro Pascual Laguna wrote: > Hello again, > > I still couldn't figure out how to find a way to split a vector in the > flowgraph (instead of digging into the c

Hello again, I still couldn't figure out how to find a way to split a vector in the flowgraph (instead of digging into the code). I am using the standalone block for the FFT and I want to split its output in halves, meaning at the output of a FFT sized fftSize I want a vector (size fftSize/2)

Thanks for the quick reply! When I said splitting in the GUI I meant using the flowgraph (instead of digging into the code) not using the sink FFT. As you say, I am using the standalone block for the FFT and I want to split its output. Is there any block to do so or any kind of snippet of code

Hi Alejandro, are you sure you want to use the FFT sinks? They basically "just" internally put the sample stream into vectors of fftlen length, then calculate the dB(abs(fft(these vectors))), and display the result. What you're describing sounds more like you'd want to use the standalone, not-grap

Hello GNUR's! I am a newbie in this community so I may pose a very simple question... I am trying to split via GUI the output vector of the FFT block in two halves, one with the upper part and one with the lower part -i.e. I don't want a duplicate of the output vector-. Say I have a FFT of 1024
