A Signal Processing Scheme for Reducing the Cavity Pulling Factor in Passive Hydrogen Masers

Abstract

A passive hydrogen maser operates so as to cause a signal frequency, fs, to satisfy a selected criterion. The frequency fs which satisfies the criterion depends on the cavity resonance frequency, fc. The derivative of fs with respect to fc for fc = fs is called the PULLING FACTOR. Theoretically this factor can be zero with a computational criterion making use of complex signal voltage samples taken at several frequencies.
