Table contains the cosine frequency components of a Gaussian peak which has a full width at half-height of 1 sec. The unit height equation for such a Gaussian peak is exp[-4(ln 2)t^2] where t is time in sec. For each frequency component f with relative amplitude A calculate A cos 2Π ft for t=0 +/-0.5 +/-1.5 and +/-2.0 sec. Tabulate the values and sum them to get the resulting peak similar to Fig.. Compare the resulting peak to the actual Gaussian as described by the equation.
