A machine is described which will perform a purely electric summation of Fourier series. The actual machine constructed can add sixteen sine and sixteen cosine terms, but there is nothing to prevent an increase in the number of terms The sum of the series can be determined directly at intervals of 6° over the range 0-2π The machine is principally intended for performing Fourier synthesis in X-ray crystallography. It can also be used for harmonic analysis.
