That is threat to old ladies, but ehum... well OK, if "Harry" is a bearded old
lady, then I guess it is OK.

On the serious side of things, there isn't very much one has to really know
when things gets complexer. As long as you stay in the linear domain, althought
being in multiples of GHz, a few things will still be true, and as you hit the
50 Hz or whatever non-standard frequency the outlets run in your home, most of
it is still very true, but you may not initially understand it to be, but when
you think of it, it still holds true. Exercises like that is very good.

Learning about inductance, capacitance and resistance and what happends with
frequency is very usefull. Also learning about transmissionlines, impedances,
reflection and transmission from changing impedance (such as extra inductance
or capacitance represents - impedance deviations) is ultrausefull too.
Combining these can be a potent drink in understanding much of the black magic
around many modern designs.

Cheers,
Magnus
