[sdiy] Resonator type filters

[Mike HEQX]

Use to have an MF10CN switched capacitor filter setup in 1984 and it was 
fun, but long gone. Maxim has the ball now and they have a good 
selection of parts. Those switched cap filters are not cheap, but could 
be awesome for animated filters or an equivalent ( sort-of ) of other 
filter circuits. I suppose many people figured this out a while ago.
