Abstract

A method is developed for handling the effect of a finite amplitude on the results of potential modulation differentiation. The procedure is applied to harmonic modulation and allows to extrapolate measured Fourier coefficients to zero modulation amplitude. It is therefore possible to use modulation amplitudes as dictated by signal-to-noise considerations avoiding dynamical broadening of the detected signal. The formalism can be easily extended to combine with dynamic background subtraction. Examples are given for soft x-ray appearance potential measurements.
