The Sheeva Plug was $99.00 The USB Audio subsystem I had to buy for it was $79.00 So, $178.00 divided by 96000 samples/sec That's 0.2cents/sample/sec Let's see how that scales using a USRP1 and a "mildly pimped out" PC USRP1 is $700 PC is probably another $700 So, $1400.00 divided by 8megasamples/sec That's roughly 0.02cents/sample/sec The USRP1 + PC is roughly an order-of-magnitude better value, when looked at in that way. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
