Abstract :
A newly developed compact digital auto equalizer and phase locked loop (PLL) system with original algorithms has solved the problems of digital auto equalizer systems using maximum likelihood error (MLE). It realizes experimentally fully automatic and practical size systems. An example of of a corresponding digital VCR is discussed
