[Discuss-gnuradio] Added functionality for pre and post samples to burst tagger

Ok, I glanced at your code quickly, here are my thoughts (some of which you may already do in files I haven't seen): 1) You are using tx_io[15] as a potentially highspeed I/O. This signal travels via the radio daughter cards and could easily lead to EMI noise issues. You could consider

[Discuss-gnuradio] Vector operation in GRC

I have a vector quantity (size 1024), and I want to do a calculation on it such that v_out[i] = v_in[i] - v_in[i-1] Is such a calculation possible in GRC? I haven't found any way to get a hold of the individual elements of a vector. @(^.^)@ Ed ___

Will that preserve the absolute positions of the original vector elements? The initial vector represents an FFT, so it's important to me that I keep the same positions. @(^.^)@ Ed On 12/19/11 4:33 PM, Allen, Cam wrote: I would probably try converting the vector to a stream, delay the stream

If you're somewhat familiar with how to write/modify blocks, it probably wouldn't be difficult to implement that functionality by making a new block that is a copy of gr_multiply_const_vcc.cc (for instance) and changing the work function to do what you want. Sean -Original Message-
