摘要:
The information efficiency of a zero-memory analogue to digital converter operating in the feedback path of a control system is considered and discussed from the point of view of known results in communication theory. Predictive quantization, where only the innovations remaining after subtraction of the predicted plant output are quantized, is recommended for reduction of the quantization noise effect when A/D converters of restricted wordlength are used.An example is given.
