Have a look at " The scientist and Engineer's guide to Digital
Signal Processing " by Steven W Smith. Quote from the Book, " this
book is written for those who want to use DSP as a tool, not a new
career". Lots of examples and not lots of maths and equations.

John,
One useful resource for phasing-type rigs is the (free)
Quadnet filter design program from Tonne Software.? This
program calculates the component values for various orders of
all pass filters (using op-amps) that approximate to wide band
90 deg phase shift networks.? The software calculates the
maximum opposite sideband suppression with these networks,
although to achieve that requires very careful construction
and setting up.?

Hi Alison,
I read about this a while back and have been looking
for some more information on 3rd order all pass
filters since then.? Unfortunately whatever I can find
is a bit over my head.? Could you recommend any
resources that might be a bit more accessible to the
self-taught amateur?? I'm about to have some free time
on my plate and I'd be interested in learning more
about this.
Cheers,
