单片机实现的双陷波数字滤波器及其应用，实现双陷波器的设计-Single-chip realization of the dual-notch digital filter and its application to achieve double-notch filter design

结构要求：采用单片机系统板实现IIR和FIR数字低通滤波器（2种方法）。-Structural requirements: Single-chip system board to achieve IIR and FIR digital low-pass filter (2 methods).

基于51 单片机的数字滤波器对于一些对性能要求不是很严格的情况 有很大的潜在应用。将FIR 滤波器移植到51 单片机上进行仿真实现，初步达到了预期效果，实现了低通滤波。-Based on 51 single-chip digital filter for some of the performance requirements are not very stringent conditions have great potential applications. The FIR filter
