In the development of a pulse position modulation analogue computer the requirement arose to control accurately the frequency of a magnetic drum. A control system was designed which compares the drum frequency to a 1000 cps tuning fork oscillator. Any deviation in phase produces a corresponding change in torque on the drum drive motor which then corrects the phase error.
As part of the over-all project a precision power supply was developed. The requirements were met by modifying existing designs. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
