[Discuss-gnuradio] Questions on the unit of Y-axis in usrp_oscope.py and usrp_fft.py

2008-01-03 Thread Brook Lin
Hi Eric and All, I found one of replies sent by Eric said that: >What are the units of the Y axis? They are the output of the digital down converter. They are not calibrated to any particular voltage level. The levels depend on the gain setting too. My first question now is what the unit exac

re[Discuss-gnuradio] al and imaginary parts of signal on oscope

2008-01-03 Thread Brook Lin
Hi All, I learn that the usrp_oscope.py shows the real and imaginary parts of the complex baseband signal coming from the output DDC. However, is red channel for the real and blue channel for the imaginary? How can I check it? Thanks, Brook -- View this message in context: http://www.nabble.co

[Discuss-gnuradio] the amplitude shown in usrp_fft.py

2008-01-03 Thread Brook Lin
Hi All, I have a question on the amplitude of usrp_fft.py. How can I print out the max amplitude by given a center frequency. For example, if there is a 99.1MHz FM station, which is detected by RXTV d'board, I can use usrp_fft.py simply detect this signal in frequency domain. Meanwhile, I want to

Would someone mind capturing some HDTV samples for me so I can plug them into atsc_rx? Or similarly, is there a repository anywhere with some sample files? I don't happen to have the daughter board enabling me to do it myself. Thanks Jeff ___ Discuss-g
