1. LF: Can't see the wood for the trees (score: 1): Author: "Andy" <[email protected]>; Date: Wed, 01 Feb 2006 16:04:03 +0100; Can someone help with what should really be obvious. I have a train of constant width pulses at a fixed repetition rate. In the frequency domain these appear as a spectral comb with spacing at the re; /rsgb_lf_group-archives/html/rsgb_lf_group/2006-02/msg00261.html (9,573 bytes)

Re: LF: Can't see the wood for the trees (score: 1): Author: Warren K2ORS/WD2XGJ <[email protected]>; Date: Wed, 01 Feb 2006 15:25:56 +0000; Andy, Unless I'm missing the meaning of your question, I believe you want the fourier coefficients to determine the amplitudes of the components making up the pulse train. Also, should you feel the n; /rsgb_lf_group-archives/html/rsgb_lf_group/2006-02/msg00263.html (11,122 bytes)

There ought to be a short cut, though, knowing the integral is finite and; /rsgb_lf_group-archives/html/rsgb_lf_group/2006-02/msg00265.html (13,242 bytes)
