<DIV><FONT face=Arial size=2>Viem, ze medzi tymi dvoma vzorkami, ktore za
periodu mam je vzdy konstatny uhol 120 stupnov. Kolko ubehlo od prechodu nolou
neviem a ani to nemam ako zistovat. </FONT></DIV>

<DIV><FONT face=Arial size=2>Zdravim konferenciu. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Mam nasledovny problem. Vzorkujem sinusovku,
stihnem urobit len dve vzorky za jednu periodu a z nich potrebujem zistit
velkost amplitudy. </FONT></DIV>
<DIV><FONT face=Arial size=2>Viem, ze sa to da matematicky vypocitat, len
nikde nemozem najst nejaky pouzitelny vzorec alebo navod ako na
to.</FONT></DIV>
<DIV><FONT face=Arial size=2>Vie ma niekto nakopnut spravnym smerom?
