Re: IM is the elephant...

Hi Scott and any others who might be interested,

Take a look at the Sziklai frequency sweep.

10 ohm || .2uF load
1050 Square wave (first 27 harmonics) 8v peak
5Khz Sine wave 1v peak

The offscale peaks at 13650 and 15750 are the 13th and 15th
harmonic of the 1050 square wave. These are a legitimate part
of the input signal.

You can see the 3rd harmonic at 15Khz. But it is surrounded by
a forest of IM. How to deal with all the IM products, seems like
the *real* first order question.
