摘要： An adaptive quantiser holds a model of the output distribution the would be obtained by inputting an expected signal as a desired output distribution. The actual input signal is monitored and the quantisation steps modified in dependence thereon so that the desired output distribution is obtained. The adaptive quantiser has application in fields as diverse a speech processing and educational test grading.
