Short summary
A method to generate broadband waveforms with low peak-to-peak amplitude based on distinct frequency domain profiles is presented, which includes random phase variation and numerical optimization. The peak-to-peak amplitude can be reduced by 71 % compared to zero-phase pulses with equal frequency domain characteristics. Used as excitation signals for impedance spectroscopy, the waveforms yield good results at significantly reduced measurement duration compared to established measurement methods.
