使用PIC18单片机实现FIR和IIR数字滤波器

资料介绍
The Microchip PICmicro
®
PIC18 family of microcontrol-
lers are popularly known for their logic and controlling
functions. In addition, these microcontrollers have built-
in hardware multipliers and multiple file pointers. These
features, along with the built-in analog-to-digital con-
verter (ADC), make PIC18 microcontrollers a compe-
tent choice for applications where logic and controlling
functions are combined with signal processing
applications.
