Harmonic Analysis of Visual Stimuli below Fusion Frequency

John Lott Brown 1

1 Department of Physiology, School of Medicine, University of Pennsylvania, Philadelphia

Data which represent the relation between modulation amplitude and frequency of a sinusoidally modulated light stimulus for constant flicker appearance have been employed to predict characteristics of rectangular waveforms which will be of the same flicker appearance. Predictions are compared with the results of an experiment in which such rectangular waveforms were employed.
