     Mmm, modulating the Rademacher functions could be interesting.
     
     Especially if you modulate only one Rademacher function, since if you 
     use the generator I've sketched (using ExOR gates) only a subset of 
     all the Walsh functions will be modified, eg:
     
     WAL(2)  = WAL(1)WAL(3)
     WAL(4)  = WAL(7)WAL(3)
     WAL(11) = WAL(15)WAL(4) <= since WAL(4) = WAL(7)WAL(3)
     WAL(12) = WAL(15)WAL(3)
     
     ... etc.
     
     I'd be interested to hear about your conclusions.

Thanks, interesting stuff.  I want to code something up and see what 
happens when you detune or PWM the Rademacher functions...
     
By the way, are there special tricks that Walsh functions do, compared 
to using pulse waves or something?
