A surface profile is sinusoidal with wavelength λ and maximum amplitude of unity. The profile is sampled at equal intervals, with the origin on the center line at a position of zero amplitude. (a) Calculate the Ra, o, and P-V distance values for this profile for the sampling intervals of λ, λ/2, 2/4, 1/8, 2/16. (b) Calculate the Ra and o values derived from the analog signal for the same profile. A surface profile is sinusoidal with wavelength λ and maximum amplitude of unity.
