我们引入了“民主”的概念，其中信号的粗量化表示中的单个比特在近似原始信号时都被赋予“相等的权重”。我们证明了这种民主表示不能达到与最优非民主方案相同的精度。
We introduce the concept of "democracy," in which the individual bits in a coarsely quantized representation of a signal are all given "equal weight" in the approximation to the original signal. We prove that such democratic representations cannot achieve the same accuracy as optimal nondemocratic schemes.
