'Another Magic Sine Wave question'

Hello All.
       Is there anyone that has used Magic Sine Waves in an application ?? I've
looked at all the data from Don's web site and it sounds like, as he would
call it, " Pseudo Science ". ( maybe because I don't know enough to tell
what is smoke or not ).
       Before I make a fool out of myself ( and spend money that I don't have )
could someone just confirm that they are not smoke and mirrors ??
       Thanks a bunch for your time.

I think that was Don's intention - to raise the capital to produce fully
functioning units as part of a business plan - perhaps with the eventual  aim
of floating the company.

It seems very reasonable and real. I see that minor variations in a regular PWM
approach can give improved results:- the 'magic sinewaves' is just a logical
extension of this - well logical in the sense that it is more focused on
producing the bit stream  directly from some formula instead of via some
iterative method - which is likely to be very time consuming indeed !

I think is worth while pursuing - but then you would be a fool if you spent
money
you don't have, then that would be a debt you'd be lumbered with ;)

Anyway I think its a worthwhile gamble at least for basic research purposes.

And you get the electrons free :)

Some say there is no magic but, all things begin with thought then it becomes
academic, then some poor slob works out a practical way to implement all that
theory, this is called Engineering - for most people another form of magic.

 The "they" being Magic Sinewaves...

The only way you'll make a fool out of yourself is by claiming that
this stuff is Magic. It's not.

I've studied various pulse streams: 12,15,24,36 and was able to
demonstrate the harmonic suppression claimed by Lancaster. I was
unable to come up with a generic formula. However, I have made
several observations and have written a program in MATLAB to
calculate the harmonic content of a given pulse stream. I can
re-post the observations and send a copy of the MATLAB program
to those interested.
