要約(日本語): Hum noise, which depends on power line frequency, is one of the most intractable noise during signal measurement. In a typical analog front-end for signal acquisition in which the hum noise exists in the model. The signal that goes to ADC still has hum noise component which is amplified by the high gain amplifier, and thus decreasing the number of effective bits of ADC which are consumed by the noise. This work propose a passive notch filter using N-path filter to reduce hum noise. Experiment result shows a more than 50dB noise suppression performance.
