Popis:	In this article, we discuss the magnetic-field frequency selectivity of a time-domain interferometer based on the number and timing of intermediate pulses. We theoretically show that by adjusting the number of pulses 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 a pulse between the initial and final pulses, which mitigates sensitivity to low frequency magnetic fields.
