[Discuss-gnuradio] Reading I & Q from a binary file

2006-06-25 Thread paul munro
Hi. I have sampled a FM signal and saved it to a file using 'usrp_rx_cfile.py'. I have checked the file by demodulating it using 'wfm_rcv_file.py' and everything works fine. I am now trying to read the file using LabView. The tutorial by Dawei Shen says the data is 16 bit signed integers in I f

[Discuss-gnuradio] Geortzel DFT implementation checked in

2006-06-25 Thread Johnathan Corgan
Checked in to CVS are a C++ implementation and stream processing block for the Goertzel single-bin DFT transform. The C++ class constructor takes the sample rate, length of the Goertzel block, and the frequency of the bin of interest: gri_goertzel::gri_goertzel(int rate, int points, float freq);
