1.0 Definition of Terms
2.0 Modes of Operation
The MF10 is a switched capacitor (sampled data) filter. To
fully describe its transfer functions, a time domain approach
is appropriate. Since this is cumbersome, and since the
MF10 closely approximates continuous filters, the following
discussion is based on the well known frequency domain.
Each MF10 can produce a full 2nd order function. See Table
1 for a summary of the characteristics of the various modes.
