Re: [Discuss-gnuradio] pulse signal generation
Hi, I did tried to generate using USRP_Source (with squarewave as option) & USRP_Sink (complex_float) blocks. However unable to see the desired o/p (I see sinewave is being generated). Pse advise if any additional settings to be made. Regds, Sudhir. On Tue, Jun 5, 2012 at 5:57 PM, Nazmul Islam wrote: > You can use UHD: USRP_Source an UHD:USRP_Sink block.

Re: [Discuss-gnuradio] pulse signal generation
You can use UHD: USRP_Source an UHD:USRP_Sink block. You can define the center frequency of transmission in that block.

Re: [Discuss-gnuradio] pulse signal generation
Hi Roberts, Greetings. Thank you for your input. I am able to bring up my system with Ubuntu 10.10 and with latest gnuradio as well able to run the grc file successfully and see the output on screen. However, would like to know how the same to integrate and generate and take the signal from USRP1 do I need to add any UHD blocks? (Typically how to interface with USRP1) Regds, Sudhir.

Re: [Discuss-gnuradio] pulse signal generation
Something to try: byte file source with one byte of 0xff, and the other 9 is 0x00. grc is attatched, but Gaussian filter is very strongly filtering it and i really dont understand it very well, which is needed for bandwidth limiting. But if you dont want any filtering, you could feed file source directly to real input of float-to-complex (with only type conversion). also attached is file you can use xxd to convert binary file to & from text file. I dont know if binary file attaches to email, but you can put this into xxd -r: 000: ff00 On Thu, May 10, 2012 at 11:50 PM, S'dir wrote: > Hi, > > I am a starter.
