Hello.
I need to make up a schematic with a voltage controlled resistor for an adaptive (state variable) low pass filter..
It is a bit confusing to explain thoroughly, but I can say the following:
Is there a way to have a circuit component (such as a JFET) acting as a voltage controlled resistor, for a WIDE dynamic range of signals/voltages (i.e 0-6 Volts) ?
So far I have come up with solutions that work with signals that vary from 1 to 2 volts, yet I need a more "flexible" VCR..
So, are there any suggestions on where to search or of any schematics??
Your help is really appreciated,
xmat.
