Hello, I am recently working with gnuradio's tx_samples.cc and USRP2. I have input files that are .sc type, which are written and saved on Matlab. I have a question though. I've noticed that signals in the input files before being saved to .sc type are being scaled, for example:
signal = sin(A); scale = 10000; new_signal = signal*scale; frwite(...) Why do we need to use this scaling factor? Thanks!
