notch amplifier

基本解釋

ECG signal sampling module design, including preamplifier, high pass filter, 50Hz notch filter, electrical level rising and primary amplifier, ADC and FPGA.
心電采集模塊的設計，包括心電前置放大、高通濾波、工頻陷波、電平抬升和主放大、A/D轉換和FPGA采樣電路。
During signal processing, choosing low noise, high-precision, low-power amplifier AD620 as a pre-amplifier, and high-and low-pass filter and the frequency notch filter removal of interfering signals.
在信號處理中選用具有低噪聲、高精度、低功耗放大器AD620作為前置放大器，并以高、低通濾波器和工頻陷波器清除干擾信號。
