K simulaci byl použit program SADYS. Jeho výstup je dále uveden
v upraveném tvaru.
Detail propustného pásma má lineární měřítko na kmitočtové ose.
Pro něj je lépe viditelné rovnoměrné zvlnění v propustném pásmu.
U nepropustného pásma je použito logaritmické měřítko.
Je zřejmé, že nebyl splněn zadaný rozdíl útlumu v propustném a v nepropustném pásmu.
Příčina je stejná, jakou jsme diskutovali u aproximace.
