| Abstract: | his paper presents a digital filter implemented by TMS32020. The hardware architecture and software programming of the filter are discussed in detail. The filter consists of the A/D conversion, the digital filtering and the D/A conversion. The TMS32020 samples the A/D converter by means of the internal timer interruption. The efficient MACD instruction is used in the digital filtering. |
