notch amplifier

基本解释

ECG signal sampling module design, including preamplifier, high pass filter, 50Hz notch filter, electrical level rising and primary amplifier, ADC and FPGA.
心電採集模塊的設計，包括心電前置放大、高通濾波、工頻陷波、電平擡陞和主放大、A/D轉換和FPGA採樣電路。
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.
在信號処理中選用具有低噪聲、高精度、低功耗放大器AD620作爲前置放大器，竝以高、低通濾波器和工頻陷波器清除乾擾信號。
