| Abstract: | In this article, we discuss the magnetic-field frequency selectivity of a time-domain interferometer based on the number and timing of intermediatepulses. We theoretically show that by adjusting the number ofpulses and the-pulse timing, we can control the frequency selectivity of the interferometer to time varying and DC magnetic fields. We present experimental data demonstrating increased coherence time due to bandwidth filtering with the inclusion of apulse between the initial and finalpulses, which mitigates sensitivity to low frequency magnetic fields.
