摘　　要：数字仪表及单片机测控系统中,A/D变换是不可缺少的环节。对于模拟量变化较快的系统,A/D变换速度也相应要求快些,才不至于丢失信息。然而A/D变换速度和成本是矛盾的。本文试以MSP43OF11X1系列单片机为例,探讨以较低成本提高A/D转换速度的方法。Not any A/D converter can be dispensed with in a test or control system Including digital instrument and Micro Processor. Usually, a higher rate A/D converter is necessary for a frequent change signal so that information does not be lost. However, converting Tate of A/D converter is conflict with its cost. As an example,I take MSP430F11X1 series Micro Processor to inquire into the approach on raising A\D rate with a low cost.
