I'm not really familiar with what are the techniques of anialiasing in use. But I can see the following way. You can calculate your tranformation for the input signal S(x_i) once And the same transformation for S(x_i)+1 again. I mean two similar input signals differing in one bit of value. So when you have two output saignals you can calculate the error due to aliasing: abs( F(S(x_i)) - F(S(x_i)+1) ) And apply some techniques to eliminate this aliasing ranging from qubic splines to plain dithering applied to the output signal. It seems to me that this is much better than oversampling. Especially for nonlinear transformations. (Or is it just a trivial thing and it doesnt work and this is not what you discuss?) nikodimka > >> i'm thinking about how to apply the technique to produce >> square clipping, or better a [0 .. 1] range of clipping, >> but the integration approach is awkward. > >I doubt that the electronics ever produces hard square clips. __________________________________________________ Do you Yahoo!?
