Results of an electrochemical experiment are shown in the figure. In each case, a voltage is applied between two electrodes at time = 20 s and the absorbance of a solution decreases until the voltage is stepped back to its initial value at time = 60 s. The upper traces show the average results for 100, 300, and 1 000 repetitions of the experiment. The measured signal to-rms noise ratio in the upper trace is 60.0. Predict the signal-to-noise ratios expected for 300, 100, and 1 cycle and compare your answers with the observed values in the figure.
