I am just working on a 36dB VCF. Plain forward design with LM13700.
First steps here: http://www.haraldswerk.de/wrdprs/ . As we know,
output level decreases with feedback (Q). This can be compensated with
increasing the output gain while increasing Q. But then the peak level
of the output will be way higher as the normal output. Which might cause
distortion in the next stage. Is there a compromise to avoid this or do
i need to select: Lower output or increased distortion?
Second thought: The filter works quite good. Does it make sense to go
for 48dB musicaly?
