Description
Delta-sigma algorithms are used to determine the desired sequence of quantum-based voltage pulses used by the Josephson Arbitrary Waveform Synthesizer (JAWS) to create calculable voltage waveforms. This data set contains a comparison (Fig 1. of the CPEM 2024 abstract) of a 1 kHz pulse pattern with rms amplitude of 2 mV without post-processing and with post-processing which modifies the problematic pulse pattern to remove incorrect pulses at the 0.75 ms pattern wrap point. In the time-domain, the pulse patterns are low-pass filtered at 30 MHz and the residuals relative to the 1 kHz ac signal are also shown. This data set also contains spectra which show the pulse patterns' voltage relative to the fundamental in the frequency domain.
