摘要: A model representative of any time-sampled, real-valued input and output digital system without feedback from to (there may be internal loops) is presented, properties that are necessary for an optimum (nonlinear) developed. The itself consists a cascade three mapping operations successively transform the sequence into M-ary valued sequence, thence N -ary finally sequence. operating routine optimality criterion function chosen permit us consider problems prediction, interpolation or synchronous operation as well wide variety loss functions. derived discussed with particular regard quadratic interpolatory then applied determination several systems. Optimum nonlinear amplitude quantizers, pulse code delta modulation systems, stepped controllers described. In particular, conditions given under which superior some remarks made concerning suboptimal systems their relation previous work.
