May facilitate low-power wearable ECG monitoring; leaves open clinical validation of signal fidelity.
A newly designed low-complexity FIR filter for wearable ECG devices reduces hardware complexity compared to existing state-of-the-art filters, potentially improving power consumption and cost.
Asgari et al. (2017) studied ECG noise suppression. Optimally-factored cascade IFIR filter vs. Conventional FIR implementation was evaluated on Hardware complexity (number of multipliers and structural adders). The proposed optimally-factored cascade IFIR filter reduced the number of multipliers from 274 to 30 and structural adders from 547 to 57 compared to conventional FIR implementation, while effectively suppressing ECG noise.
