摘要
Abstract
ENOB-data out of size are found in part of module's ADC circuit in the testing of some missile-borne computer.The fault tree analysis is made of the affecting factors one by one, and it is found that the signal source frequency plays an important role in ADC circuits.The fault position is accurately located by theoretical analysis and algorithm simulation.The problem is solved by redesigning clock circuit and changing the input of the signal.关键词
