The output of the lowpass filter is a dc voltage. But the value is not
in the range of my VCO control voltage(0 to 1v). How ot pull down the
dc votage into 0 to 1v? I tried diode, not work.
Another thing is that the feedback affect the output of the Lowpass
filter. it makes the output of LPF a different value compared to using
2 independent input
at the PD. what is the reason? Thanks.
