Bandpass measurements in the electroretinographic electrode circuit

In the experiments in this study band-pass measurements in electroretinographic electrode circuits were done for the first time, according to the information presently available to us. Our experiments show that in the much faster band-pass assessment by analysis of sawtooth and square waves no major error is involved. It may be concluded from our results that the recordings of ERG potentials are not changed by the characteristic properties of the electrode circuit in the frequency range of interest.
