EP06 VCFs - Elektor Formant Modular Synthesizer Overhaul

Published on Nov 19, 2016 Marco Reps

"In this episode we take a look at the voltage controlled filter 12 dB and 24 dB modules and their theory of operation. One module needs a bit of work because an op-amp has passed away. VCFs have almost no applications apart from music electronics, but the integrator amplifiers, they are based on, are very interesting and useful."
