【Abstract】 This paper reveals a fact that the effect of quantization errors on measuring precision may be masked by the noise associated with input signals. And by computer simulations, the quantitative relations between this effect and the selection of A/D bit numbers or the quantiztion levels in data compression, are given.更多还原
