Adjustable crystal oscillator with acceleration compensation

摘要

A variable oscillator is disclosed which is adjustable by a user to a desired frequency. A variable reactance element is inserted in series with a crystal resonator, the variable reactance element having characteristics which are dependent upon the conditions of acceleration. The characteristics of the element which is a compensator are substantially complementary to the characteristics of the crystal resonator to balance out said variation of the crystal resonator during conditions of acceleration. There is also provided a variable reactance network connected to the oscillator to adjust the operating frequency of said oscillator.
