Those osc are a thing of the past...

I beg to differ.


Bring a junk am broadcast radio near your computer, you will hear literal
dozens (well, a bunch anyway!) of osc's freqs going on there, probably not one
being generated by a colpitts, hartley or pierce osc circuit...
And, with the proper processing, all those waves could be a sine...

In all likelyhood, the master clock oscillator for the microprocessor
is a Pierce xtal oscillator. All of the other garbage is derived from
that. There may also be plug-in cards with their own clock, most
likely another Pierce.

In case you've forgotten, these are -digital- circuits, sine waves
need not apply.

Why you guys think that the computer guys have invented some new
-magic- oscillator is beyond me. Wait a minute..... maybe I understand
after all.
