ABSTRACT
To promote the electrophysiologic diagnostic efficiency, the program for calculation of the total power in the frequency domain and of the area in the time domain of the electroretinogram was designed. The total power is calculated by integration of the squared power spectrum obtained by Fourier transform (Parseval theorem) in the time domain. The dominant power is the power of the dominant frequency in power spectrum and is calculated by integration of the squared peak area spectrum. The sectional inegration of the squared power spectrum can be established by manual input. The inplemented software also has the functions that calculate the summed amplitud and area of the oscillatory potentials in the time domain. And it performs each functions by selection of pop-up menu with mouse to use conveniently under graphic interface, compatible with UTAS-E2000 system.
