[sdiy] Switched cap filters

[Paul Perry]

I could well be wrong (I didn't really get totally to grips with the data
sheet)
but, it looked to me as though the clock is 100 times the centre freq, and
if
this is so, then working over the full audio range, when you are at the low
end,
the clock is well in the audible range (even for my old ears).
Whether this leads to a problem I do not know.
