Assessing the Contribution of the Oscillatory Potentials to the Genesis of the Photopic ERG with the Discrete Wavelet Transform

Table 3

Time domain (TD) derivation of the TD%OPs contribution to the photopic ERG from previous studies (column 1). Column 2: TD%OPs values are presented in increasing order and were computed as the sum of OPs (SOP) amplitude divided by the associated b-wave amplitude and multiplied by 100. Column 3: the type of filters that were used. N/A indicates unspecified filter type. Columns 4 and 5: ERG and OPs cutoff frequencies that were used for bandpass filtering. Column 6: the attenuation that was used at the specified cutoff frequencies. N/A indicates unspecified attenuation.
