compared picture transmission using one and two sidebands. With the same overall bandwidth, the single-sideband system carried finer picture detail. Its quadrature component made the detected electrical waveform appear badly distorted, but the photographs were affected much less than the waveform suggested. They also found that maintaining a small transmitted current for the darkest parts of the picture reduced the visible error.
