CA3080 filter

[Stewart Pye]

Hi, this is my first message to the list.

On looking at the CEM 3320 notes I noticed that for all pass cofig. the
output of the first stage goes into the input of the second stage and to
the cap of the second stage, and so on for the succeeding stages. In low
pass config the out of stage one goes only to theinput of stage 2 and all
the caps go to ground. This is also how CA 3080 filters such as the
polyfusion vcf work. This led me to think that I could uuse the polyfusin
vcf as a 4 stage phase shifter,switchable to lp vcf with 4pdt switch
between caps and ground.
Before I try this Ithaught I'd see if anyone has tried this.
Any info would be appreciated.

thanks,

Stewart.

ps, great list.
