Correct but, the complex magnitude must not exceed 1.0, or else you may clip in the DSP. > And what happens if you try to send values larger than 1.0? truncation of the most significant bits For example, the DQPSK block will transmit symbols at +/-1 +/-j. These constellation points will clip in the DSP of the FPGA if you have the cordic tuned to a non-zero frequency. I recommend that you characterize your output before using the max dynamic range of the DAC. -josh _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
