Figure 13. Filter Characteristic (First Stage = black, Total = Blue)
In Figure 13 the simulated characteristic of the entire filter
is shown, in both variations, for the first stage (black) and
total filter (blue). The normal and low−cost variations are
superimposed, showing that the variations are minimal.
However, when the tolerance on the values is also loosened,
a bigger variation in the characteristic is observed.
Figures 14a and 14b show a monte carlo analysis for
resistors of 1% and 10%. It is advised to use resistors of at
least 1% accuracy.
