[Discuss-gnuradio] Sample Rate

2008-01-28 Thread Richard Jaeger
I have been playing with a number of the examples - FM NB and WB receivers, AM receiver, etc. The sample rate appears to default to 64 MSPS, but I have been unable to find where that default rate is set. Where is it defined? Can it be changed from the examples themselves? For example, 64MPS

I asked the same thing a year or so ago, didn't get much of an answer. AFAIK, there are no software hooks for the digital I/O pins. What we ended up doing was editing the verilog such that the sign of the real component sent to the BasicTX dboard came out on 1 I/O pin, and the sign of the imag

Thanks for your help! (Yey!) But I have another problem. It doesn't read the file correctly. For your info, the file has been generated by MATLAB using the -ascii setting. Therefore the file contents look something like this. 1.7011476e+000 -1.6834541e+000 2.6309809e+000 2.1425840e+000 -

Hi! Thanks for your reply! Yes, the file contains a string representation of floats. So I suppose that the file should contain a binary representation of floats? And, yes I did start my flow graph. I would like to apologize for not including it in my post. But, rest assured that I ran my flow
