Pulse signal generation

Hi,

I am a starter. How to generate 100Hz (10% duty) pulsed signal using
gnuradio & usrp1

Any help would be highly appreciated.

Thanks & Regds,
Sudhir.

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:
0000000: ff00 0000 0000 0000 0000

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.

You can use UHD: USRP_Source an UHD:USRP_Sink block. You can define the
center frequency of transmission in that block.

Thanks,

Nazmul

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.
