Abstract
A microwave bridge circuit for measuring frequency modulation noise signals arising in low power, high frequency sources having a highly non-constant FM noise versus baseband frequency characteristic includes amplifying and filtering means for excluding signals in frequency ranges beyond the field of interest and frequency response compensator means of attenuating signals outside the primary range of interest.
