[Discuss-gnuradio] GNURadio Companion LPF

[Yeo Jin Kuang Alvin (IA)]

Hi all,

 

Apparently, I tried connecting the USRP Source to a Low Pass Filter and to a File Sink, I get overflows “OOOOOO”. However, when I removed the LPF, there is no overflow. The question is, why is this happening? Is the Low Pass Filter in GRC done in the FPGA or in the computer itself? I am using USRP B210 and my sampling rate is 6MHz.

 

Is there a solution to this?

 

Thank you in advanced!
