I just received my shiny new N210 in the mail a few days ago, to experiement with EEG acquisition, analysis and machine learning classification for captured brainwave activity. However, the FedEx fellow was kind enough to leave the package on the front stoop where it got rained on. There was s

Patrik, I'm not sure I understand what you're saying. I know my knowledge is limited especially my coding skill (I come from a more theoretical background). And I think the best way to learn is to watch others do it first and practice. I'm sorry if that's completely off your point. Johnny On Mon

Very interesting ideas. Thanks Marcus for sharing! Unfortunately I don't have enough background in compiler to implement such ideas. I'm in the phase of learning GNU Radio, keeping up with its fast development is already a big task for me. I'm certainly willing to do something *to* GNU Radio when I

Re: [Discuss-gnuradio] sampling rate of USRP2

2011-08-29 Thread Nick Foster
The USRP2 is fixed at a 100MHz sample rate. Are you using the polyphase resampler? Its CPU load should be significantly less than the "regular" rational resampler in Gnuradio. --n On Mon, Aug 29, 2011 at 2:22 PM, Marcin Szelest wrote: > Hi, > > I'm using USRP2 as transmitter of DVB-T signal. >

[Discuss-gnuradio] sampling rate of USRP2

2011-08-29 Thread Marcin Szelest
Hi, I'm using USRP2 as transmitter of DVB-T signal. Is is possible to decrease default USRP2 sampling rate from 100MHz to multiple of 9,142MHz? Now I'm resampling signal but this solution is time consuming and I'm not able to get real-time performance of modulator. In fact I just need to slow down
