[Discuss-gnuradio] How can we find out the IF frequency of the signal coming out of RTL-SDR source block

Hi, I am trying to receive a GPS signal and I am using RTL-SDR2832U, and an antenna with 40dB gain. According to my research, the signal coming from the satellite is at RF, and it gets downconverted in front-end to IF (Intermediate Frequency). Now, I need to remove that IF from the signal coming

[Discuss-gnuradio] How to get the code of Low pass filter block of gnuradio

Hello, I need to know the code of LPF BLOCK of grc. How and where can I find it? Thanks, Priyanka ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Re: [Discuss-gnuradio] How to get the code of Low pass filter block of gnuradio

Hello, as far as I can see, the low pass filter block only exists in GRC. The relevant XML description for GRC can be found here: https://github.com/gnuradio/gnuradio/blob/master/gr-filter/grc/variable_low_pass_filter_taps.xml The underlying source for firdes can be found here: https://github.com

Re: [Discuss-gnuradio] Ways to improve latency of a low bandwidth stream

Ok, I believe I have made up my mind. Since that I'm looking at a packetised burst transmission system, the best way I have to remove latency from the system is to flush the buffers in the gnuradio flowgraphs. I can do this easily on the receiver side: once that I finish receiving my RF data an
