Investigation and Continued Development of the Idealab Fourier Transform Analog Computer

摘要

The report describes the modifications of the Idealab Fourier Transform analog computer and the results obtained from these modifications. Indicated in the report is the final figure of a resolution for an input of 2249 sin wave cycles within one frequency increment (14% of the (sin x)/x crossover). Also indicated in the report are the methods and circuitry used to obtain this accuracy and operator instructions for the new controls. Emphasis is placed on the electronic and engineering considerations of the monitor panel, white light actuator, velocity servo, precision clamp and oven control. A complete set of blue prints covering the modifications is provided at the end of the report. (Author)
