[Discuss-gnuradio] gr_math.h addition, SDR Forum

I made an addition to gr_math.h today in an attempt to get some stalls for branching out of code where we have an if statement run on every bleeding sample. gr_branchless_clipping is the new addition to gr_math as a static inline float. It may surprise that calls to fabs and multiple

Hi, I think your problem is simple, you are wrong in two thinks, 1) You chooses to input 50 KHz signal to your USRP, and I think you are using the Basic RX daughter board, which have an RF transformer that needs at least 200KHz input signal to pass it without distortion. 2) You used a DDC
