Thanks! I need to run a Spice simulation of this. The peak amplitudes of
both the tone (in one filter) and the noise (in the other filter) would be
the same after clipping, but the tone filter output would be less when fed
with the clipped noise than with the clipped tone. But is this an
improvement over not clipping the signal?

Again, I need to simulate it!

Thanks!

Harold
