Calculating Significant Wave Height in both Non-dir/Directional Wave Spectrum

Hi all,

I am now doing an embedded module specifically to calculate the significant wave height (Hm0) for the ocean wave. As I know, Hm0 = 4*sqrt(m0), where m0 is zeroth order of the wave spectrum.

For testing purpose, i using function generator to generate a 100Hz sine wave with 3Vpk-pk signa

why can't i print in the message area? [Last Updated On: November 7th, 2009] [Originally Added On: November 7th, 2009]
