Function Description
The LC block is a discrete simulator of derivative element

$C\left(s\right)=\frac{\mathtt{\text{td}}\ast s}{\frac{\mathtt{\text{td}}}{\mathtt{\text{nd}}}\ast s+1},$

where td is the derivative constant and nd determines the influence of parasite 1st order filter. It is recommended to use $2\le \mathtt{\text{nd}}\le 10$. If $\mathtt{\text{ISSF}}=\mathtt{\text{on}}$, then the state of the parasite filter is set to the steady value at the block initialization according to the input signal u.

The exact discretization at the sampling instants is used for discretization of the $C\left(s\right)$ transfer function.
