Abstract
ONE of the common characteristics of all non-linear electrical devices, such as vacuum tubs, is the generation of harmonic frequencies in which, with a pure sine wave input, the output contains a series of multiples of the input frequency. For more than a decade, piezo-electric oscillators have been used as sources of reference frequencies because of their high stability. Since it is desirable to operate these oscillators at a frequency higher than those of the standards—usually at 100 kc.—a sub-multiple generator, or frequency divider, is required to secure the desired lower frequencies.
