本文叙述了采用δ—∑调制实现非递归数字滤波器的方法。所推荐的方法能使简单的δ—∑调制用于模拟数字转换。这种实现非递归数字滤波器的方法允许使用微处理机,而不需使用外部的快速乘法器。并且实验结果已表明:使用8位微处理机能得出令人满意的结果
This paper describes the use of delta-sigma modulation non-recursive digital filter method. The recommended method enables simple delta-sigma modulation for analog-to-digital conversion. This method of implementing a non-recursive digital filter allows the use of a microprocessor without the need for an external fast multiplier. And the experimental results have shown that the use of 8-bit microprocessor can yield satisfactory results
