SECONDARY_STANDARD_FOR_100_AND_10_kHz

Published:2009/7/2 0:52:00 Author:May | From:SeekIC

Combination of 100-kHz crystal oscillator and 10-kHz MVBR provides 100-kHz harmonics far up into high-frequency spectrum, with each 100-kHz interval subdivided by harmonics of MVBR using two FETs. Oscillator is tuned to crystal frequency whh Miller 42A223CBl or equivalent slug-tuned coil L1. C1 ad justs crystal frequency over narrow range for standardizipg against WWV transmissions. Synchronizing 100-kHz voltage is injected into MVBR through R5.-R. P. Turner, FET Circuits, Howard W. Sams, Indianapolis, IN, 1977, 2nd Ed., p 127-129.
