摘要

一种改进的分析给出了对唱机:装置提出在惠特尔(1989)实现可靠的记忆从不可靠的组件。结果表明，对于有N个这样的组件的大系统，可以可靠地存储KN + o(N) nats的信息，并确定了K(容量C)的最大值。进一步证明，当处理单元的数量M不大于N阶时，可以实现正容量(评估)。

The antiphon. II. The exact evaluation of memory capacity

An improved analysis is given of the antiphon: the device proposed in Whittle (1989) to achieve reliable memory from unreliable components. It is shown that for large systems of N such components one can reliably store KN + o(N) nats of information, and the supremum value of K (the capacity, C) is determined. It is moreover shown that a positive capacity (which is evaluated) can be achieved with the number M of processing units of no more than order N.
