引言数字系统固有的量化误差是妨碍短字长计算机应用的报本原因。七十年代初,Moore等人提出“随机参考点量化”(RRQ)的理论,实现了量化特性的线性化,从而得到在有限字长系统中消除量化误差的可能性。此后,RRQ在信号处理的许多方面(如相关函数估计,随机计算,数字滤波器等)得到应用 Introduction The inherent quantization error of digital systems is a newspaper cause that hinders the use of short-word computers. In the early 1970’s, Moore et al. Proposed the theory of “random reference point quantization” (RRQ), which realizes the linearization of the quantization characteristics and thus the possibility of eliminating quantization errors in a finite word length system. Since then, RRQ has been applied in many aspects of signal processing (eg, correlation function estimation, stochastic computation, digital filters, etc.)
