Hello all, I want to know how I could possibly find out the complete details about the BPSK-Signal generated by the benchmark_tx.py GNU Radio script. Should I look at the code and at which file respectively? Thanks in advance. -Sebastian- ___

[Discuss-gnuradio] duration of uhd_rx_cfile script

2011-12-14 Thread Sebastian Döring
Hello all, I just measured the time the execution of uhd_rx_cfile.py takes all together. I used N=2, samp-rate=1M and the rest was left to the default values. In theory the taking of the samples should take T=N/B=20ms but I had to discover that the whole process is taking about 2s.
