Weird VCF idea! (SC-filter!)

[Erik Schuijers]

Hi all,

I have another weird idea for making a VCF. It's by using the MF-series
SC-filters by National Semiconductor. It works really easy. Has anyone else
ever thought about it?

The only backdraw is that the cutoff frequency should be controlled by a
VCO. In order to keep voltage controlability.

For those who are interested: check out national's homepage and search for
the switched capacitor filters!
