碩士 === 國立臺灣海洋大學 === 電機工程學系 === 94 === In this thesis, we have developed a Propagated-Carry Selection(PCS) multiplication based digital notch filter which can be applied in the ECG signals. A main idea for applying PCS Procedure to more significant part in constant multiplication is to decrease the area compared with other kind of multipliers. Simulation results show when a 0.3333 pi rad/sample notch frequency and 0.2063 pi rad/sample 3-dB rejection bandwidth digital notch filter is designed, it increases 44.5% precision and decreases 67.3% area.
