[BC] Re: Super Modulation and distortion

[Alan Alsobrook]

You know I'm not sure on this weather it is necessarily distortion or 
not. I haven't looked into how different asymmetry devices are producing 
their output. But thinking about it a bit, if it's done by actually 
shifting the DC level of the wave form, prior to sending it to a AM 
transmitter, the recovered wave form would be distorted as a result of 
the asymmetry.
