There's no "exact block" to solve your problem. You have a specific task, and you'll have to design a specific solution. We can't do that for you, as much a we'd like to. Best regards, Marcus On Sat, 2018-05-12 at 18:10 +0200, JONNY LEYIKUN wrote: > Thanks for the feedback! Mr muller > To be ho

No, 15 kHz is not "very minimum", it's impossible. Your console will contain information that the UHD picked a different, higher, sampling rate. Your "I picked 15 kS/s to get a clear audio file" doesn't make much sense; this is not how digital communications work! I'm afraid you'll have to be way

HI Jeff Long Yaah 15K is very minimum to use in USRP sink I use 15K sample rate in order to get clear Audio File. but I also use large sample rate in USRP sink but the result is more or less the same ___ Discuss-gnuradio mailing list Discuss-gnuradio@g

A USRP doesn't work at 15k S/s, and your audio sink probably doesn't work at 120k. On the TX side you have 2 different blocking sinks (audio and USRP) which can mess things up. Not sure about the rest of it. It seems like there might be some filtering and oversampling missing. On 05/10/2018 12
