Implementing IIR Digital Filters
INTRODUCTION
This application note describes the implementation of various digital filters using the PIC17C42, the first member of Microchip’s 2nd generation 8-bit microcontrollers. The PIC17C42 is a very high speed 8-bit microcontroller with an instruction cycle time of 250ns (@ 16 MHz input clock). Even though PIC17C42 is an 8-bit device, it’s high speed and efficient instruction set allows implementation of digital filters for practical applications. Traditionally digital filters are implemented using expensive Digital Signal Processors (DSPs). In a system the DSP is normally a slave processor being controlled by either an 8- or 16-bit microcontroller. Where sampling rates are not high (esp.
