Abstract :
We present some results concerning the effects of changes in system parameters on the picture quality in PCM transmission systems. We restrict our attention to low-resolution monochrome still pictures, and discuss in particular the effects of the number of samples per frame, the number of brightness levels, the scanning pattern, and the channel noise, with a view to the optimal choice of these parameters.
