摘　　要：提出了利用中低速Ａ／Ｄ转换器对两类中高频方波信号幅值采样的方法，不仅可以降低仪器成本，而且能有效地避免误采、失码等现象。By using the A/D transformer with middle low speed two methods of the magnitude sampling are proposed for two types of square wave signals with the middle high frequency in this paper. It has been proved that those two methods can not only reduce the instrument cost but also avoid effecliely sampling and code lossing.
