A high-accuracy static time delay device utilizing transistors

THE fixed voltage-time integral value determined by the swing of the flux level of a rectangular hysteresis loop magnetic core from one saturation level to the other has been exploited in a variety of ways, e.g., in magnetic amplifiers, saturating transformers, etc. Nevertheless, extensive utilization of the integrating capabilities of cores has been limited by the functions which associated circuit components are capable of performing. Employing junction transistors as circuit components, however, opens new possibilities of using this characteristic of saturable cores to perform a variety of useful functions.
