Hi karan ,
Thanks for reply .
well ya in gnuradio also if i set the value of samples/symbol below 2 it is
throwing me an error .
So is there any specific reason behind using the value greater than 2?
and is that higher the value of samples/second the smoother will be the
waveform? please correct me if i'am wrong .
Thanks
Sandhya
