  • Abstract
    The concept of short-time waveform distortion (SD) permits us to express in numbers the subjective quality of fine details in a TV picture. Various schemes to do so are briefly reviewed in order to find a method that will apply most advantageously for the system MU. S. and Canada (4 MHz, 525 lines). Having chosen the T-step technique, an oscilloscope graticule is presented together with methods of determining short-time waveform distortion arithmetically without a graticule.
