(Color online) Spectrographic analysis of sideband-based STM. Multiple comparisons of the proposed sideband-based generation method with a classic numerical solution for a midpoint-to-peak modulation depth of 20 dB (40 dB peak-to-valley). (a) Spectrogram of the STM created with the proposed Bessel function sideband approach using a sideband extent of five (ten sidebands), (b) spectrogram of the STM created by exhaustively evaluating the explicit form for exponential modulation, and (c) ratio of the Bessel function sideband-generated stimulus to the explicit form of the stimulus. Note that the colormap limits are $\pm 6\times {10}^{-4}$ dB for the spectral power ratio.
