Frequency-divider chain uses pairs of rectangular hysteresis-loop magnetic cores as counting elements. Has high accuracy and stability. First core (ladle) is driven to saturation by each input pulse. Constant-voltage integral output from ladle core drives second bucket core. With appropriate turns ratios of windings, bucket core can be made to walk up its hysteresis loop in any number of predetermined steps. Successful single-stage dividers have been made up to scales of 17, with reliable operation from 10 to 50 kc.-A. Rose, Magnetic-Core Divider for ITV Sync Generators, Electronics, 31:15, p 76-77.
