Maybe splitting hairs, but to my way of thinking the overall function of the circuit is analogue, the 4093 conveniently reduces the component count, its functions could be done with discrete components but at increased cost, increased power consumption and space

Yes, I think a quad op amp could be configured to do the same as the 4093 (with extra resistors), but it would still require a nice DC supply, although not necessarily a 3 pin regulator.

...and thank you for the pot taper info.
