In a reverse normal pulse voltammetric experiment, a complex voltage scan is applied to the working electrode in an electrochemical cell. The waveform is the sum of a growing pulse (Curve A in the Figure below) and a staircase (Curve B in the Figure below). The resulting waveform is seen in the Figure below, Curve C.
The pulse and the staircase both grow by the step height with each repetition. The resulting waveform may also be thought of as a staircase that has a pulse back to the starting potential at the end of the step.
