Illustration of Filter Loss and Deviation
Especially the "linear deviation" is a measure for the quality of the coefficient set. The
lower this value, the better the approximation is. Several runs of the program can result
in different values for the linear deviation because of the random starting parameters the
algorithm uses. In general, it should be possible to reach a value of less than 3dB for the
"lin. deviation".
Optimization Mode "target function"
The algorithm tries to compensate the input function in such a way that the addition of
this input function and of the filter functions of FX or FR is as close as possible to the
target function. The target function must be given in a file.
Before starting the algorithm, the sampling frequency points of the target function are
adjusted to the sampling frequency points of the input function. ARCOS-SP PLUS
checks if each sampling frequency point of the input function has a corresponding
sampling frequency point in the target file. If a sampling frequency point is not found in
the file, then the amplitude value of this sampling frequency point is interpolated by
making a linear approximation from the two points closest to the desired sampling
frequency point. Thus the algorithm can work with two curves not having the same
sampling frequency points.
