A. Time Domain Results E-Dot and H -Dot)
Further investigation since the initial findings were published has shown that the E—dot and H -dot data, digitized using the HP digitizing scope, required some preprocessing before any analysis could be achieved. It was found that the digitizing scope had an accuracy of only I b out of 6 b for vertical resolution. This error was enough to produce a dc offset, seen by a straight line during integration, and by dc terms during Fourier investigations. By using an averaging process, this error due to the dc offset was eliminated and all further analysis was performed on this corrected data.
