Has anyone tried building a Frequency shifter using Weaver's method?  
Either analogue or digital.

I'm asking out of interest, rather than any immediate intention to build 

All of the synth related designs I've seen seem to be based around the 
phasing method, using either an analogue dome filter or digital Hilbert 
transform to impart the 90 degree phase difference.  I was looking at 
Weaver's or "the third method" of SSB generation relating to an SDR 
discussion at work the other day, and it looks like a good candidate for 
a modern DSP implementation.
