Example dynamic spectra of selected bursts from FRB 20240114A, illustrating the distinct morphologies discussed in Section 4.1. In each subplot, the left panel shows the burst spectrum across the full UBB frequency range, where the vertical dashed lines indicate the re-binned frequency bands, while the right panel presents the dynamic spectrum (bottom) in the UBB band where the burst is detected, together with its frequency-averaged temporal profile (top). The temporal profiles are fitted with solid red curves, with dashed vertical lines marking the measured burst widths. The burst spectra were generated at a frequency resolution of 1 MHz and a time resolution of 0.5 ms. Channels affected by RFI were masked and replaced by median values for visualization. See Section 2.2 for details of the fitting methodology.
