A Decade Frequency Generator From a Single Frequency Origin

Abstract

Development is in progress on a technique and an equipment which will derive, from a single fixed frequency source, an output which is variable in decade steps of one cycle through 10 Mc over the frequency range of one cycle to 100 Mc. The system herein described synthesizes this output by the multiplication, selection, mixing, and successive division of a fixed 100-kc frequency. Uniqueness and simplicity are achieved by the fact that the 1-cycle, 10-cycle, 100-cycle, and 1000-cycle control units are of identical operation and construction and can be used interchangeably. Additional identical units may be added to produce increments to as low an order as desired (0.1, 0.01, 0.001cycles, etc.). The configuration of the system is such that no adjacent signals requiring filtering lie closer than 5 percent. The lowest fixed frequency generated is 10 kc.
