Description

A 24db/Octave lowpass filter. which corner frequency is variable by control voltage. The filter characteristics can be changed, too.
Using it as sine wave generator is possible. This filter needs no capacitors at the inputs and output, thus you can use it at very low frequencies. It is working with OPAMPs, resistors, capacitors and eight diodes.
