To develop a specialized machine capable of rapidly summing Fourier series to eliminate computational bottlenecks in X-ray crystallography.
Represented fundamental sine curves of arbitrary amplitude using sets of mechanical or electrical impulses.
Implemented a selective arranging switch to map impulses to corresponding wave-numbers and routed them into counters to sum terms across all variable values simultaneously.
The system computes the complete summation of Fourier terms concurrently for all values of a variable rather than evaluating them sequentially.
Successive combined cycles of the impulse generator and selector switch enable rapid, automated synthesis of crystal structure factors.
