You can use the programs found in gnuradio-core/src/utils/read_float_binary.m etc to read those files from matlab or octave where you can resave them in a format that you want.

Hey slimchao, Thanks for the reply! I tried gr.file_sink(). It writes something in a txt file, but when I open it it is not in readable format. Is there something that I can do to make it a readable .txt format for the MAt lab, where every sampled value is written as float value on a new line?

[Discuss-gnuradio] How to store recieved signal (time, voltage) in .txt format
Hey all, I want to store the signal I recieve from my USRP+XVR2450 in a text file, in 2 columns(1st clumn time and 2nd column I and Q voltage levels from USRP at each sampling time). So, how can I do this in the Python? I want to do this because I prefer to do the signal processing on the baseband signal in Mat Lab(by importing the txt file data) rather than defining a new signal processing block in python.
