Hello Jeff Long, Thank you for your answer. I am really new to GNU Radio and DSP, so I am not sure to have understood what you said: do you suggest to get rid of the "stram to vector" blocks ? I also do not know what a single pole IIR filter is, I will document myself and try to implement that so

Thanks, I tried a very basic example and was trying to monitor data rate using nethogs with a different sample rate. At a signal sample rate of 9.6MSPS, nethogs sees about 59MB/s of data. I wonder if that could be improved in anyway, or whether the sample rate of an actual wired lan connection mig

Hi Mobi, Thanks for your response. Actually, while waiting for an answer yesterday, I did exactly as you suggested as a trial and it worked beautifully. I was coming back online just now to let Gnuradio Community know I had solved my problem when I saw your response. Thank you very much! Regar

The firdes.low_pass_2(...) function in my GRC has stopped working

Hello GNURadio Community, I have used the firdes.low_pass_2(...) function in many of my Gnuradio blocks in the past to pass filter coefficients to my blocks and it has always worked. Yesterday I opened one of my GRC that uses his filter function and it showed an error. The specific usage was: fir
