Talk:Voltage-controlled filter

Voltage controlled filters have a variety of applications besides analog music synthesizers (bandpass filters in radio circuits that are controlled by the bias voltage on a variactor diode, etc.) Also, considering the various applications what is "high" and "low" frequency is completely arbitrary, 15khz would be considered a high frequency signal in an audio application but a very low frequency in one dealing with radio frequency signals. Perhaps there is a way that this entry can be specifically related to the use of VCFs in analog music synthesizers, or maybe rewritten to be more general?

What references are missing?

I don't really see what references should be in this article. scoofy 22:16, 10 August 2006 (UTC)

All Wikipedia articles require references. Have any good ones for VCFs? Ted 3000 22:40, 8 November 2007 (UTC)
