Abstract :
It is the evaluation of the subjective fidelity which is of primary importance in any communication system where humans constitute the final information receiver. A method showing how to generate grey-tone increments by computer for displaying simulation results is described. The method is based on the fact that, by over-printing well-defined characters of a commercially available chain printer, grey tones can be produced. The set of characters and the number of overprints used is presented in matrix form.
