Many thanks in advance for anyone who reads this article.

As a hobbyist electronician I have come across a real problem.
For a certain project, I would need an oscillator with digital,
LOGARITHMIC adjusting (32-bit, 1000 x log) and a HUGE range,
1 kHz to 100 MHz. Is this at all possible?
Then the next problem would be just to divide this signal into eight
lines, so that the lines would pulse (change state, whichever would be
the easiest) alternately, in order. I mean: Line 1,then line 2, then line 3,
and at each input pulse from the oscillator the next line would be activated.

This oscillator-divider pair would be used to control 8 memories, whose
signals would be each in turn given to a D/A converter. 

BTW, is a VCO voltage/frequency ratio linear or what? Negative or positive?

Please, if you read this message and know something about logarithmic 
frequency control, PLEASE! email to mlukka(at sign)kannel.lut.fi
