Re: FF: More Treble Wanted!

R.G.	Re: FF: More Treble Wanted! The clipping is so soft that the tops of the waveform never quite squash out to flat. If you have a mixed bass and treble signal, you can still see treble wiggles on the tops of limited bass swings. The original article on using a diode connected MOSFET in EDN had scope traces that showed exactly that. Note that the content is reduced, but not lost - in fact that was one point mentioned in the article. The higher frequency information was not lost, but remained in the waveform until it was massively overdriven. "Preserved" is probably not the right word - "not lost" is, I think.
