If my i(t) and q(t) samples are defined as follows: i(t) = x(t) * sin(wt) q(t) = x(t) * cos(wt)
then, given i(t) and q(t), I can recover the magnitude of x(t) as follows: |x(t)| = sqrt(i^2(t) + q^2(t)) But how can I recover the sign of x(t)? For each of the four possible combinations of the signs of i(t) and q(t), x(t) could be either positive or negative. Thanks. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
