Spectral and temporal metrology with bandlimited functions and finite-time measurements
Åukasz Rudnicki, Tomasz Linowski
We perform an analysis supplementing the metrology toolbox in the time-frequency domain. While the relevant time-frequency-based metrological protocols can be borrowed from the spa…
