I have a USRP1. I'm trying to run the tx_waveforms UHD example.
While using tx_waveforms, we have some parameters we nwwd to provide at the command line.
1. What is the parameter --spb, samples per buffer. And generally, what is this buffer?
2. What is the relationship between spb (sample per buffer), duration (number of seconds to transmit) and rate (rate of outgoing samples) and wave-freq (waveform frequency in Hz)?
