fFrequencyCut-off frequency
normalizedBooleantrue= true, if amplitude at f_cut is 3 dB, otherwise unmodified filter
initTypeInitModelica.Blocks.Types.Init.NoInitType of initialization (1: no init, 2: steady state, 3: initial state, 4: initial output)
x_startReal[n]zeros(n)Initial or guess values of states
y_startReal0.0Initial value of output (remaining states are in steady state)
alphaRealif normalized then sqrt(2^(1/n) - 1) else 1.0Frequency correction factor for normalized filter
