[Discuss-gnuradio] how to use Log Power FFT module in python

[nansai hu]

 

I want to do some function in frequency domain and just writen a C++ block already.

Now, I just want to use GRC to constuct a front end and connect to my own block.

 

The interface bewteen these two is a power vector of FFT results and  I use a Log Power FFT module in GRC.

 

My question is Log Power FFT module in GRC seems that have a very strange output format(not stream or vector),

So what is the format of that module and How clould I use it if my C++ block have a float vector input(512 points power result of FFT).

 

Thanks
