Ali-Silvey类的距离措施适用于设计用于二进制检测系统的量化器的问题。为了找到最佳的解决方案的量化的概念必须稍微推广，并建立必要的条件，在这种情况下的量化器参数的选择。本地，或小信号，条件也来自这些被认为是同意渐近结果的基础上皮特曼效率。作为一个例子，研究了在加性广义高斯噪声中检测恒定信号的四电平广义量化。
The Ali-Silvey class of distance measures is applied to the problem of designing quantizers for use in binary detection systems. To find optimal solutions the notion of quantization must be generalized slightly, and necessary conditions are established for the selection of quantizer parameters in this context. Local, or small-signal, conditions are also derived and these are seen to agree with asymptotic results based on Pitman efficiency. As an example, four-level generalized quantization for detecting a constant signal in additive generalizedGaussian noise is investigated.
