A cheaper high-speed ADC + cheap FPGA, or a more expensive ADC with built-in DDC and CIC decimator, etc. -- 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
