Abstract
The use of wide frequency-range equipment has forced the designer to consider many of the possible sources of distortion in order to determine limits for their effects. The work described in this paper was performed to ascertain the improvement provided by the new Bilateral sound track as well as to set allowable tolerances for commercial equipments. It is shown that the amount of distortion due to aperture alignment can be reduced readily to negligible amounts, particularly when the Bilateral Sound Track is used, since here both sides of the sound wave vary, thereby reducing the amplitude required for full modulation. The analysis has been limited to variable amplitude film and is restricted to a sine wave.
