Abstract :
A simple yet accurate method is described for characterizing digital recording channels in terms of linear and nonlinear intersymbol interference and noise. The method is based on echo cancellation techniques, enables recorder operating conditions close to actual use, and delivers a joint portrait of the disturbances rather than isolated assessments. Experimental results for a high-density digital video tape recorder are included
